Hi This is my first post on here and I'm really hoping someone can help! 2 months ago I took ownership of a cat (Charlie) from the mother of my children (with full agreement from her I should add!), as she was looking to give him away and my eldest felt he would be happier with me as well as obviously not wanting to part with the cat she's had almost her whole life. He is a 11 year old neutered male and I already have a 1 year old neutered male so after a few days of doing it the wrong way and trying to get them used to each other (and a few trips to retrieve Charlie from his old house), I took advice from my vet who suggested keeping Charlie in for 6 weeks and keeping them completely separated, as well as investing in the Feliway Friends plug ins (I have one in each cat's main room they spend their time in). I did this and have started letting Charlie out again over the past couple of weeks, although he will only actually leave when he thinks I'm not looking and will not come near the door when I open it for him, and the two cats are still separated. However, every single time he goes out, no matter what I do to make an escape beyond my property difficult, he refuses to come back inside and still eventually escapes and returns back to his old home every time. When he goes back there, my ex-partner and my kids are under strict instructions not to feed him, not to let him in the house, and I've asked her to be the one to return him rather than me collecting him as after a few retrievals he runs away whenever he sees me approaching. I've also asked her to do this as soon as possible so he spends less time re-settling there, but she isn't sticking to this part of it and has been there for over 24 hours as I write this (I tried to retrieve him myself just now but he was hiding out of sight somewhere). I've put a lot of effort over the last 2 months into trying to make him feel at home, with lots of attention, treats, etc., but despite him becoming more affectionate towards me than he has ever been before, nothing seems to be working and I'm completely out of ideas. Can anyone help???
