My Tegu is gaining weight!

[stainthedane]

Hey Guys,
My tegu (Cygnus, or "Siggy") is a year and a half now, and is 3ft long.
Siggy's been 3ft for quite a few months now, which I'm not use to, cause usually it's non-stop Growing!!! Well......I'm going to call Siggy "her" for now, we're not 100% sure, but her girth is starting to grow!

I just want to keep on top of it.
I'll take her out for longer periods of time and watch her diet, but is there anything else you guys specifically suggest?
Should I be concerned that her length has slowed down in growth, or is this normal for her age?

probably normal. if shes going to hybernate she needs fat storage, so i wouldnt put her on a diet.

I don't hibernate her, I keep her temperatures the same all winter. She didn't hibernate last year either.
I was worried for a second that she was developing MBD, but there's no reason for it, I haven't deprived her of calcium at all, etc.
But perhaps she wants to hibernate... I don't know, I'll keep an eye on it, just so long as she doesn't become obese!
