baza and rsvp 100% spot on, had cats all my days and you don't own them.....you kinda rent them....... They decide....... and I just let mine get on with it
potty64 I have to disagree. The effluent that comes out of the back of my dog doesn't half pen & ink. And I have to collect it from the four corners of the garden. My cat's turds are much less offensive in the hooter department and he kindly does them all in the dirtbox, one tip and they're all gone.
