Hi Rainbowzz ---

I say go for the rats - I have had them as pets and they make wonderful pets. They are really smart and, if you handle them a lot, loving and sweet. My last 2 - Willy and Harry - were funny, sweet boys. If you keep them in an aquarium just make sure to keep it really clean as ammonia from a urine build up can wreck their lungs and run up vet bills.

Have fun
