Most shelters have cats they can/will only home as indoor only - cats with FIV positive, hearing or visually impaired, those who were previously kept as indoor cats, for example. We have an indoor cat and as long as you provide them with plenty of stimulation and interactive play, it works fine (with the right cat).
Oh dear that is sad, sadly most shelters like you to have a garden to let a cat out into, have you considered a stay indoors cat like mine? They can be expensive but you can get some reasonably priced from people or breeders with ex breeding cats for sale.
If I was still breeding I would give you a kitten... that's no help at all, so sorry.
they barely come home and havent done for years, we try locking them in but they escape and they just want to be next door, after years of low level fall outs with neighbour we had a discussion last night and I have given her all their food and said I think they have made their choice. I actually feel a little bit relieved that it is finally sorted and I know they are being well looked after and where they want to be. So this is now a cat free house.
