never mind, they are tersa sphinx cats, SO COOL! Unfortunately they prefer pentas and we have no such thing. Lucky I drove by when I did, my mom was literally peeling them off her ravaged plants and throwing them in the street. I took all nine of them home with me. They are very large so I am thinking they are nearing cocooning. I am not sure what I am going to do with them, either drop them off at a nearby nature center where I know there are some flowering plants, or maybe just give them some dirt and see what happents.
