I hope you don't mind me throwing my hat in the ring...
I've got 3 sulcatas that have been putting on about 1/2 pound, or less, of weight per year. Speedy (i got one of those too) is my poster child. I believe it is a she but at 9 inches SCL I think it's still too early to tell. She weighs in at about 5 lbs and she is coming up on 7 years old.
The point is that growth rate is highly variable for tortoises in captivity and I like to drive this point home to relieve any worry in new tortoise keepers. If the tortoise is active and healthy with a good weight, the growth rate should be of no concern. I'm convinced that there is no such thing as 'too slow' or 'too fast'.
>>Graham can I ask you something?
>>At 7 years of age do you know how much your tortoise weighs?
>> Ours has a long story, we don't know who originally owned her, so we don't know her age but after her being here for 3 & 1/2 years she's grown to be so large that at 55 pounds I can't lift her to clean her either.
>> The few times she's pooped in her house & then sat on it, my hubby has had to hold her up while I try to wash her plastron. That's something that's gotten to be very difficult so in winter when she does this.. she's a dirty old woman lol.
>>In winter though the heat mat or "pig blanket" dries up the poop fairly quickly then it just falls off of her, thankfully.
