Crazy things cats will do.
I have just recently gotten a new cat. His name is Gizmo. The day I got him it was really crazy at my house. I already had one cat whos name is Pounce. He has been the only pet in the house for almost two years. So he was not happy at all to see this stranger in his house. So all that night all I could hear was this hissing from Pounce but at least no blows where thrown. But in the same night that is how the second cat got named. I dont know if you all would remember the movie Gremlins or not but he sounds just like one. So in between the hissing that is what I heard.
