Hey guys, so every time I soak my two year old red foot Faven, I can't get the water to stay warm! I have this plastic container I soak her in, it's like a large food container that I took from my kitchen and designated as hers, so don't worry about germs or anything but I was just wondering if you guys had any tips? I don't want her to get cold, but I also want to be able to have her in there for a good twenty minutes, thank you!
