Why do cats sometimes go to someone else's house?

Answer 1

Another reason is that the cat is simply too stressed in its old house, i.e. new baby, or not enough attention. My cousin had a cat move in with her from across the street because the owner became ill and was in hospital for four months and the caretaker of the property wasn't meeting the cat's needs. Cats are opportunistic and will seek a safe and loving environment over a stressful one.

Perhaps there is another cat over there. My cat Molly goes out into the backyard and has 2 other cats come and play with her. Either that or the person next door is feeding your cat (you know how cats graze when they eat.) LOL Marcy
