Rats are such awesome pets! This is the third pair of rats that I've had. They're medium fancy rats, if you go by the pet store's tags... although I guess they've gotten pretty darn big, hehe.
These two don't do tricks, unfortunately. My last pair, I acquired from my boss when they were still babies, and they were very easy to train. They didn't do tricks, per se, but I let them run around my apartment freely, because all I had to do was clap my hands twice, and they'd run back to their cage. As far as I was concerned, that's the best trick anyway. LOL! But the two I have now - Gwendolyn and Llewella - were a bit older when I got them, and they still don't even like to be held, so I think tricks are out of the question.
No baby rats out of these, either. I've thought about buying a male rat and breeding, but then I think, "what the heck am I going to do with a dozen little rats?!" I couldn't keep them all, and I will NEVER sell them back to a pet store, because 99% of pet store rats up here end up as snake food! But holy cow, are baby rats ADORABLE. Someday....
