Webster was full grown when I got him at 10 months. He looks pretty much the same and weighs the same as he did then.
Kim I honestly can't remember...it seemed like she just kept growing and growing forever but that's probably because we were told she would top out around 25lbs...
Mira grew vertically until she was about 12-14 months but didn't really finish filling out til she was about 3yrs. She's still physically maturing a bit I think.
