Just moved to a new appartment with two cats.

Hello, I have just recently moved into an appartment which is much smaller then the house I was living in before. I have two 2 year old cats, boy and girl.(Mona and Oliver) They used to be allowed out side at my old house, which they loved, but im my new appartment in the city, letting them outside is just not possible. So I was wondering if there will be and side effects in moveing and if there can be problems with confinement in the apartment. I have noticed that mona the girl cat has been eating alot more then usual. Anyone have any tips or suggestions?
Thanks.

I suggest you get a cat tree to sit by the window for them to enjoy looking out. Be careful if you have a patio door that they don't go out - they might forget and jump off.

You could also get a small enclosed "run" that could be put on the patio for them to sit in and be protected.

Cut back on the food if they are not getting as much exercise.

Thanks, ill look into buying a cat tree. ill have to make some room by the window.
