Every cat is different, mine just happen to be particularly well behaved, but it did take some time to teach them boundaries of the yard. We just slowly let them out and followed them around, rounding them up as needed until they got the gist of what is and is not okay. They come when called, but all they really do is eat the grass and watch the birds lol. I’ve tried a harness before because Id really like to be able to take two of them to the beach, but they both hated it.
