rat question

[RickyNY]

okay soo I went to go thaw out a rat for Pretzel the other night. Usually it takes about 2 hours for a rat to thaw out for me, but after two hours I checked on it and it was still pretty frozen. (this was a larger one than usual so that is probably why). I didnt have time to wait for it to thaw out longer (it was 2 am at that point and I had class in the morning) so I threw it back into the freezer. Is it still safe to feed? Ive heard that if you let it thaw out it starts to grow bacteria and what not.

Also another question.. Ive heard that at some point you dont feed your ball python every week, like when there fully grown. How do you know when that is?And then how often do you feed them, once a month? Ive had Pretzel for about a year now and got him as a baby @60 grams, now he is around 800 last time I weighed him. He is on small-to-medium rats.

I always wondered the same thing when my royal was a baby, but he self-regulates his eating.
I too was feeding every week until he was 880 grams and a year old (I keep weight and feeding records), and then he stopped eating for over a month. When he resumed eating I tried to feed every week but he would refuse every other rat, so I went to every 2 weeks and he never refuses a meal now.
