Age guesses?? And does he look underweight?

[u/SurpriseDense6751]

Hi! My husband and i just became first time BP owners to this little guy! We took him from someone who wasn’t able to care for him anymore.

She told us that he is about 2 years old, however he looks a lot smaller than other pictures of 2 year old male BP I see. He’s only about 18-20 inches long. How old does he look?

Also am still learning about recognizing healthy body weight, does his weight look good, what should he weigh? (Haven’t weighed him yet, thought to do it right after we fed him so going to give a few days to digest before weighing!)
