Abandoning a pet is never a harmless decision. It is a serious act with severe consequences for the animal, the owner, and the wider community. While some people may think leaving a pet outside or “setting it free” is kinder than surrendering it to a shelter, the truth is that abandonment almost always leads to suffering, and sometimes death. It’s important that we all understand the harm caused by pet abandonment, its impact on society, the legal consequences, and why it should never be an option. 

The Harsh Reality of Pet Abandonment

Rising Statistics: Singapore and Around the World

Singapore

  • In 2022, the Animal & Veterinary Service (AVS) investigated 310 abandonment cases, up nearly 38% from 225 in 2021. The numbers had previously been 230 in 2019, and 251 in 2020.
  • The SPCA reported attending to 285 abandoned animals in 2023, almost triple the 96 in 2022. Of those, about 127 were cats, up from 45 the previous year.
  • One report noted that abandonments at least doubled, while adoption numbers hit a 5-year low of only around 600 animals adopted in 2023. Rabbits accounted for roughly 100 of those abandoned cases.

Globally

  • In the UK, shelters are facing a 34% increase in abandoned cats this year.
  • In Scotland, the number of pet surrenders rose by 25% in 2023, with nearly 7,000 animals handed over. 
  • In India, particularly during monsoon season, abandonments have surged, as rising care costs, housing issues, and underestimation of long-term needs lead owners to give up pets.
  • In major US cities, the population of homeless community cats has exploded. In Los Angeles alone, estimates suggest 1 to 3 million stray cats, spurred by unaffordable pet care and rising surrender rates.

Abandonment vs Surrender

These are different actions. Abandonment is when an owner leaves a pet without care or supervision, often on the streets or in public spaces, leaving the animal to fend for itself. This is illegal in many countries and can cause severe suffering or death. Surrender, on the other hand, is when an owner responsibly gives up a pet to a shelter, rescue group, or another safe and approved home. While surrender should be a last resort, it ensures the animal remains in a safe environment and has a chance at rehoming, rather than being left in danger.

Common Reasons Owners Abandon Pets

Across studies and reports, several key themes emerge:

  • Financial strain: Rising costs of food, veterinary care, and living expenses are pushing owners to surrender or abandon pets.
  • Changing circumstances: Returns to work post-pandemic, relocation, housing restrictions, or altered family dynamics (like allergies or caregiving responsibilities) leave owners unable to care for pets.
  • Behavioural issues & lack of training: Pets without early training may develop challenges that owners feel ill-equipped to handle.
  • Impulse adoptions: Many animals adopted during the pandemic were decisions based on convenience or novelty, not commitment. When the reality of pet ownership sets in, they may find themselves unprepared for the responsibilities, leading to abandonment.
  • Housing limitations: Landlord restrictions, lack of pet-friendly options, or moving abroad are often cited as top reasons for surrender.
  • Owner health or personal issues: Illness, personal crises, and inability to maintain care can lead to relinquishment.

The Harsh Reality of Pet Abandonment

Harm to the Pet

When a pet is abandoned, it instantly loses the safety, shelter, and care it once had. Domestic animals are not equipped to survive on their own, especially in urban environments.

1. Physical Suffering and Low Survival Rate 

Abandoned pets are very different from feral animals. While feral animals are born and raised without human care, abandoned pets have lived with people and relied on us for food, shelter, and safety. When these pets are left to fend for themselves, they are often confused, frightened, and unequipped to survive on their own. Unlike feral animals, they lack the skills to find reliable food, protect themselves from danger, or cope with extreme weather. This sudden loss of care puts abandoned pets at high risk of injury, disease, starvation, and death. Many abandoned pets, especially very young ones who are not weaned do not survive. 

2. Psychological Trauma

A pet that has known human companionship will feel deep confusion, distress, and fear when suddenly left alone. Studies show animals exhibit grief-like responses including withdrawal, loss of appetite, disrupted sleep, and depression-like behaviour. Many develop lasting behavioural problems such as aggression, anxiety, or extreme fearfulness, making them harder to rehome even if rescued.

3. Overpopulation

If the abandoned pet is unneutered, it can breed with other strays, adding to the stray animal population. This leads to more suffering, more disease spread, and increased pressure on already crowded animal shelters.

Strain on Animal Shelters & Welfare

Animal shelters and rescue groups often end up dealing with the consequences of abandonment.

1. Overburdened Shelters 

When pets are abandoned, many are eventually caught and brought to shelters. But most shelters operate at or beyond capacity. Overcrowding can mean less space, less attention for each animal, and, in some heartbreaking cases, euthanasia due to lack of resources. 

2. Financial Burden

Caring for abandoned pets is expensive. Shelters rely heavily on donations and volunteers. The more abandoned animals there are, the more resources they need for food, medical care, and rehabilitation. This can stretch their budgets to breaking point.

Impact on the Community

Pet abandonment is not only a problem for the animal. It affects the entire community.

1. Public Health & Safety Risks 

Stray animals can spread diseases and parasites, posing public health risks. They may also be more susceptible to injury or illness due to their vulnerability.They may also cause traffic accidents by wandering into roads or injure people if they feel threatened and bite.

2. Ecological Damage

Feral cats and dogs can prey on native wildlife, upsetting the ecological balance. They compete for resources with other animals and can spread diseases to wild populations.

3. Introduction of Invasive Species

In some cases, abandoned exotic pets, like certain reptiles, birds, or even small mammals, can become invasive if they survive in the wild. These species can outcompete native wildlife for food and habitat, potentially leading to the decline or even extinction of local species.

Legal Consequences for Owners

Many people do not realise that abandoning a pet is a crime in many countries. In Singapore, for example:

  • First-time offenders can be fined up to SGD 10,000 and/or jailed for up to 12 months.
  • Repeat offenders can face fines up to SGD 20,000 and/or 2 years in jail.

Courts can also issue disqualification orders, banning offenders from owning pets for a set period.

Neglect, such as failing to provide proper care or not trying to recover a lost pet, is also a criminal offence with similar penalties.

Internationally, countries like the United States and the United Kingdom treat pet abandonment as an act of cruelty, with offenders prosecuted and penalised accordingly.

Emotional Impact on Owners

Abandoning a pet can have lasting emotional effects on the owner and their family.

Guilt and Shame: Some owners experience deep regret after abandoning a pet, especially if they later learn of its suffering.

Impact on Children: If children witness abandonment, it can cause confusion, sadness, and loss of trust, and can send harmful messages about responsibility and compassion.

Common Challenges with Abandoned Dogs & How to Overcome Them

Fear and Anxiety

Many abandoned dogs are wary of humans due to past neglect or mistreatment. They may cower, tremble, or hide when approached, and some may be reactive to strangers or loud noises. Some may panic when left alone, barking, howling, or destroying items. Give the dog time and space to adjust. Avoid forcing interaction. Let the dog come to you. Use gentle, positive reinforcement (treats, praise, toys) to build trust.

Start with short absences and gradually increase the time apart. Leave interactive toys like treat-dispensing puzzles or even lick mats to keep them engaged. Licking can be a calming, self-soothing mechanism for dogs. Practice “calm departures” and “calm arrivals” so leaving and returning home feels normal. In severe cases, consider working with a qualified dog behaviourist to create a tailored socialisation plan.

House-Training Issues

Some abandoned dogs have never been house-trained or may have lost the habit due to stress. You’ll need to re-establish a consistent feeding and toilet schedule. Take the dog out frequently, especially after meals and naps. Use a potty training spray to encourage the dog to urinate at the preferred designated areas. Praise and reward them immediately after they toilet in the correct spot. Avoid punishment as accidents are often the result of confusion, not defiance.

Health Problems

Abandoned dogs may have untreated medical issues such as skin conditions, parasites, dental disease, or malnutrition. Take your dog for a full veterinary check-up as soon as possible. Follow your vet’s recommendations for vaccinations, deworming, diet, and ongoing care. Keep records of all treatments for future reference.

Lack of Basic Training

Some abandoned dogs have never learned basic commands or leash manners, making daily walks and safety harder to manage. Ensure you get a properly fitted dog collar, and a no-pull harness & leash for better control during walks. Begin with short, positive training sessions using treats and praise. Focus on essential commands like “sit,” “stay,” and “come.”

Food Guarding or Resource Aggression

Dogs who have gone hungry may guard food, toys, or sleeping spots. Feed in a calm, quiet environment. Avoid taking food away suddenly. If you need help, talk to a vet or a dog trainer to help curb the behaviour.

Difficulty Socialising with Other Pets

An abandoned dog may not know how to interact safely with other dogs or cats, especially if they’ve had negative past experiences. Introduce them slowly and in neutral territory. Use leashes for control, reward calm behaviour, and supervise all early interactions. Go at the dog’s pace. Rushing can cause setbacks!

Alternatives to Abandonment

If you can no longer care for a pet, here are humane options:

Rehome Responsibly

Find a trusted new owner through your personal network or verified adoption channels. Always screen potential new owners to ensure they are committed and capable of caring for the pet long term. 

Contact Animal Welfare Groups

Many organisations can assist with temporary fostering, and rehoming. Some include:

  • SPCA (Society for the Prevention of Cruelty to Animals) – Tel: 6287 5355 (24-hour hotline), Email: enquiries@spca.org.sg, Website: spca.org.sg.
  • Animal Lovers League (ALL) – Tel: 9697 3491, Email: info@animalloversleague.com, Website: animalloversleague.com
  • Causes for Animals Singapore (CAS) – Tel: 9793 7162, Email: info@causesforanimals.com, Website: causesforanimals.com
  • Voices For Animals (VFA) – Facebook: www.facebook.com/VFASIN/ 
  • SOSD (Save Our Street Dogs) – Email: info@sosd.org.sg, Website: sosd.org.sg 

Work with a Trainer or Vet

For behavioural issues, professional help can often resolve the problem. 

Seek Financial Assistance

Some charities offer subsidies for pet food or medical care. The SPCA's Community Animal Clinic offers subsidized veterinary services, including check-ups, vaccinations, and microchipping to low income families with pets.

Neuter/Spay Your Pets

Prevent accidental litters that can add to the stray population.

The Harsh Reality of Pet Abandonment

Abandoning a pet is never the right choice. It causes physical and emotional harm to the animal, strains shelters and communities, and can lead to serious legal trouble for the owner. Domestic animals depend on us for their well-being. When we take them in, we accept the responsibility to care for them for life. If you’re struggling to keep your pet, reach out for help. There are always better options than leaving them to suffer alone. A pet is for life, not just for when it’s convenient. Owning one is a commitment, and breaking that commitment through abandonment is both cruel and, in many places, criminal.
