Chiming in on crate training. Coco (our dog) has been crate trained since we got him at 7 weeks. He loves his crate. He is crated at night and when we arent home or if I'm unable to be in the same room with him for any length of time. He only has access to the living room. As he gets older and more trust worthy he will be able to roam more in the house. Yep, he still gets into mischief. Also, We dont have accidents in crate. Luckly, since he turned 1 yr old last week he can hold his bladder longer and I'm not getting up 2x in the night for potty breaks.

I've never heard of crate training a cat.
