I'm happy to hear Nico and Blue are doing well and it's not causing any stress for Nico. That's awesome!
Funny, I had it in my mind that Nico was bigger. I guess I didn't catch that he's a SI. My Tucker is a red sided and is between 420 and 450g. At 450 he's chunky, so we work him back. Probably not the best, and his vet isn't thrilled, but I don't mind a few extra grams on him over the winter when the house is cooler. Insulation, you know
He was 435 last week, so I'm happy with that.
My first ekkie Patches was a Grand, and right at 400 all the time.
