I totally forgot that McKay appeared on SG1 first! You'd think I'd remember (I've seen all of the episodes too...multiple times )

Rodney has grown into quite the personable critter. He's not at all food motivated which is surprising. He's pretty picky when it comes to food, too, although more towards functional foods. He isn't a fan of sweet treats or any sort of "human" food. He prefers seeds, nuts and the occasional dried fruit. He loves being petted and having his head gently scratched. He'll even head bump like a cat when he's in a cuddly mood.

Edit: I've tried to handle him with citrus smell on my hands and he runs away. I think he very well may have a thing against oranges!
