Yep. That's all this is. And that's all it needs to be.
I'm constantly surprised at how wonderful guinea pigs are—they can be housetrained, they recognize their owners, they kiss you and nuzzle you, and they are content to just hang out on your lap on the couch. This is to you my wonderful Gish! My favorite moment in the summer is when my guinea pig and the dog hang out and eat grass together in our backyard.
