When I first got my two kittens almost a year ago,I did the keeping them seperate from my older two cats. I kept them in the kitchen,its huge and warm and they had plenty of space to play and explore. Once they were all friends,I still kept them in the kitchen to sleep so the older cats had peace at night and we could all sleep. Now fast forward a year, and they still sleep in the kitchen.They have a bed each,their litter tray and food and water plus space for toys should they wake early. If I dont put them to bed by 11.30pm they take themselves. They cause no trouble or noise and dont wake us up.I think its great they have their own space and they're happy but a friend just told me she thinks Im cruel locking them away. She thinks they should have the run of the house even though they are happy going off to bed and never play up to go. After all,we put children to bed in a room with a closed door but do you think Im being cruel?
