So, I have a rat that had such a strong will to live(he jumpedout of two BP tubs during feeding) ........so I let him. I named him "Templeton" cause he's such a junk food junkie. Anyways, evey am and pm I pick him up, let him sit on my shoulder for a bit, and pet him, and give him peanut butter cookies. Well, this morning, while I was petting him in his tub, he started thumping his tail. I've seem the tail thumping before when I used to breed rats, but this was ususally when males were acting agressive toward one another. He was enjoying the petting, and he wasn't trying to bit me, or anything. In fact, he tilted his head while I scratched under his cheeks, clearly indicating he liked it. But why would he thump his tail at me? Perhaps someone with much more rat experience than I knows about this......(help? plz?)
