We don't want him there. So my big seventeen year old chases him back into the house with a loud bellow any time the cat sneaks out. The cat can move. He also nerfs him when Ranger sneaks into his room. Ranger recognizes the nerf gun.
Ranger likes to sneak into the garage.
It's where I keep my chinchillas. So far he has escaped. Chinchillas have a powerful scent they can put out in their urine when provoked. You would know it once you've smelled it. Ranger has been lucky.
