I've just got 2 indoor cats, have never had indoor cats before-other ones used to go out during day then home at night to sleep. They are 8 years old and quite placid, havent really played with any toys. Very needy at times and Miaow a lot for attention. Haven't quite figured out what they are trying to tell me yet! I'm worried they will get bored being at home all the time-looking for suggestions please.
