Our cat is too lazy to jump the gates, he will sit on one sit trying to scratch at them to get us to open it up.

We now leave him gated in the kitchen/laundry/sunroom side of the house (his food & kitty litter is in the laundry) and he has plenty of space seeing all he does is sleep all day. I find this much easier now that DD is running around the house and I don't have to worry about her chasing the cat and once she is in bed at night we then open the gates up and he has free reign of the house again.
