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...
to be honest, I would want a dog, but I just don't have the time for it, cats are just better suited for my lifestyle / work patterns etc.
