Ok here is the deal my Normal male is weighing in at 498 empty. He has been powering down food since I got him in Jan going from only 120 grams to 500 around April.
Feeding:
1: refused
2: small rat
3: refused
4: refused
5: 2 adult mice
6: refused
I feed on a 5 day schedule. Everyone else has been eating fine. I mean the pastel was off for 2 weeks but he was in shed so no biggie.
Now he is in shed himself which I fine weird. That is all he has eaten in like a month and he is in shed?
Well on that last feeding (tonight) I just recently go myself a colony of ASF rats and go 2 extra to experiment with. Well he refused the ASF. Not live, not stunned, not dead. So now I think to myself what is his deal? After he goes through shed I am def going to get his poo tested that is for sure but other than that what should I try.
BTW i have tried live, f/t (warmed up), leave the f/t in there overnight, make the rat bleed, ASF's. His feeding response has gone down BIG time since switching to rats. He had a killer response on f/t mice but now he is like w/e to rats. Only takes them in they are live (maybe).
I was thinking about getting a gerbil. I heard these are like crack. Now if I do this will he addicted and not want to eat anything else?
As far as weight wise he has been from 475-550 since early April. He seems to be more apt to eat after I poo. Then he is all good.
Plz help.

Also for temps and caging.
He is in a rack system (16 wt). The temps stay 90-93 hot and 77-79 cool i the tub but lately it has been going down to 86-87 randomly for some reason. Only does it on the top and bottom shelves. it's flexwatt cut in half but hasn't done this before except for the past 3 weeks. Thermostat is a Ranco. Building a new 41 qt and it is on the way. Should be ready by next week.
