My name is Logan!

My cat Logan 7yrs old is a sweet boy. He loves to snuggle and cuddle all day. He is house trained but loves to sun bathe. He love tuna he won't eat any fowl or red meat strictly fish. He drinks from a filtered fountain he is very spoiled. Unfortunately he no longer gets along with his mother cat, Nessa, who is also just as loved and spoiled. I have raised Logan from birth and Nessa was 3 months old and already pregnant when I rescued her. It has been months and I have tried everything I have researched I have spoken to numerous vets and nothing is working. I currently keep them separated by leaving Nessa in my room and Logan has free range of the house otherwise Logan will fight with Nessa. He is a wonderful cat I am very saddened by rehoming him but I am at my wits end.
