You can never replace a furbabe who you have had the privilege of being owned by........................but you can give a loving home to one(or two!) who desperately need it!!
Gizzy and Jerry could never replace Oscar , but they are little darlings in their own right and I'm sure that somewhere Oscar is looking on and purring!
Beavis was obviously lonely after we lost Oscar , and he has in general been fine with the new boys , even cuddling up on one occasion.
Honey and Twinkle may need some time to accept a new kitty , but I am sure they will be quite happy with a new friend to play with eventually
