Thank you so much for the reply. I was beginning to despair, lol.
Yeah, he's eating 2 pinkies every 5 days now with ease, and it doesn't slow him down at all. It was the abundance of activity that made me think he may need something bigger.
I just fed him the last 2 pinkies out of the pack, so I'll be off to the pet store soon to buy some fuzzies.
Thanks again!
