Sorry if I missed it, but I couldn’t find the size for Anubis in this thread. However, there is no “normal’ size. It depends upon the parents and genetics.
As as you can see, there is a huge difference in sizing between my two adult males.
Many Boa’s growth rate slow down to a negligible amount around year 5 or 6. Other’s growth rate may still be noticeable for more years, especially a BC.
At 12 years old I thought Punch was pretty much maxed out. But from year 12-13 he added a whole foot! And that’s feeding 1/3-3/4 less than the previous owner fed him, PLUS 1/2 the frequency.
Things aren’t always engraved in stone with these snakes. You should not worry, Anubis looks like a healthy, well cared for Boa.
She’s just over 3 feet and then some, maybe 4 inches. And pushing 700grams here soon.
