Alf was weighed on May 8th and weighed 343 grams, we got her a new UVB bulb a ouple of weeks ago and she really stated to eat again,she had not been wanting to eat real well. No,her UVB was not out of date,as a matter of fact I replaced it like 3 weeks early.We weighed her yesterday and she weighs 392 grams,is that too much to gain in 3 weeks? I am so happy that she is eating,I just don't want her gaining too much weight too fast. BTW we always use the same scales,we don't own them,but they have to be accurate because of the work my husband does,he has to use them.
