Our neighbours will be moving away soon. Due to age and health concerns, they are not able to take their cats with them. Their cat, has always been in and out of our house. He's absolutely adorable, and we are more than happy to adopt him.
My question is, how do I go about settling him in, and making him realise that he now lives here rather than next door? Would it be a good idea to keep him inside for several weeks once the neighbours leave? We have another cat already. They get on surprisingly well. In fact the neighbours' cat is the only other cat that my cat will tolerate. The two of them together have often tried to chase away 'enemy cats' that come into the garden!
Any advice gratefully received. Thank you!
