Trust me I started at hoppers when she still wasn't eating the pet store I got her at recommended trying a pinkie to see if she will eat. As for warming them if they are frozen I put them in hot water and let them de-thaw.
age wise she is about 5-7 months I believe not sure on her weight but she doesn't feel or look like she's lost weight.
I have regular heat lamps one 70 watt on her cool side and 100 watt on the warm side. I have 3 seperate temperature gauges one on warm and cool plus one in the middle. Don't have a current humidity gauge (previous one stopped working needed to wait for a day off) 40 gallon I believe and she has 3 hiding huts.
