Crying when wrestling
My two cats seem to get along pretty well for the most part. They never hiss or growl at each other (except when the larger one returns from the vet!), they don't mind each other when eating, they play together often, they groom each other, they sometimes sleep together, and they will wrestle. However, it's this last activity that from time to time concerns me: Usually they make no sounds other than tossing and turning, but occasionally the smaller one (about 10 lbs.) makes this awful sound when the bigger one (about 17 lbs.) is on top of him: "Aaaaaaaaaaaaaaaah! Aaaaaaaaaaaaah!" (almost rhymes with "cat" or "rap") And left unchecked the pitch and eventually volume grows. I'm very concerned that the little one is about to get more and more hurt, so I yell "Hey!" and put a stop to it. And then moments later, they act like nothing is wrong; they are friends again. I'm scared to just let them go at it, especially with the size imbalance, but should I?
