My cat Mittens found out that it's not fair that Alex (dog) gets to go outside and he cant. He's been outside a couple times but now he sits at the door meowing until someone will open the door. He is quick to get out when someone comes in and out. I had a collar on him with is name and the phone number but that somehow he got stuck in his mouth the other night and was flipping out. That's the second collar he's had. Is there a certain kind of collar that he wouldnt be able to get stuck in his mouth like that?
