Is Your Pet Living a Double Life? Stopping Cats from Visiting Neighbors in 2026

Your cat might be cheating on you. A rescue cat owner recently shared a viral story about their high-maintenance pet being "slowly adopted" by an upstairs neighbor. Despite receiving the best treats and expensive toys, cats are notoriously fickle and will often wander off if they spot a better deal elsewhere.

Why Cats Stray: The Science of Feline Infidelity

The most common motivation for a cat's wandering eye is food. According to the pet site Kinship, if a neighbor offers more appetizing or frequent meals, a cat is likely to return. Stress at home—such as new pets, loud noises, or home renovations—can also drive a cat to seek refuge in a calmer environment. They aren't necessarily looking for a new family; they're just looking for a stress-free zone.

The Hidden Dangers of 'Secondary' Feeding

While it might seem harmless, a neighbor's generosity can be dangerous. Linda Ryan from International Cat Care warns that cats with conditions like diabetes or kidney disease are particularly vulnerable when eating uncontrolled meals. Toxic foods like onions, garlic, or chocolate could be accidentally fed to them. Furthermore, the risk of crossing busy roads to reach their 'side dish' increases the chance of accidents.

GPS Trackers and Legal Boundaries

If you suspect your cat is unfaithful, experts suggest installing a GPS cat tracker or a microchip cat flap to monitor their routine. Amicable communication with neighbors is usually the best first step. Legally, the landscape is changing; for instance, the UK's Pet Abduction Act 2024 now recognizes feline sentience and makes taking a pet without authority a potential offense.
