why does one need more than 1 bike? Same difference. Only joking. I just think I am not giving enough time to entertain the cat and if she had a play mate, then when I am busy they could play with each other, but guess this only happens if they were born a pair / been paired up since kittens etc...
My cats look after each other a lot, but they are brother and sister. They still like a lot of human attention, thankfully, but they're quite independent too.
Can I ask why you feel another cat would satisfy you?
