Aww, who's your vet? He sounds nice.

LOL My rats weigh sooo much less than your's! A pound is 454 grams, and Icarus is only 283 grams, and Frisco is only 375. LOL I didn't think yours were that much heavier.

Put a warm compress on his cyst everyday. That's what I did with Icarus's. After about a month, it finally opened up. It was yucky lol.
