What's the length of a cat's memory? We moved about 4 weeks ago, taking the cats with us, while the house was underpinned. We'll be moving back in about 3 weeks. Will the cats remember the place, even though it will smell different - will we need to keep them inside in case they try to find their way 'home', forgetting they're there already?
In the past we have left our cat in the cattery for a couple of months and she had no problem when she came home. She recognised where she was at once .... heading straight for the feeding bowl!. I wouldn't worry the cats will settle back as thought they have never been away.
No problem . Cats remember places, hunting trails and the like from sight more than anything else; smell is not very significant to them in recognizing places . Your cats will be on their old 'hunting grounds'. They have enough sense to stick by the person who feeds them, too !
My cats appear to have a very long memory. My family (including 2 cats) moved abroad for 3 years and came back to the same house. We used to let them out of a particular window in the kitchen and they remembered! As soon as they got back and had explored, they both went and sat by the same window, just as they had 3 years before.
