We have a male and a female that I uncrate in the morning when I get up. They head to the bedroom immediately to get under the covers with my wife..
The male is warm, but the female is hot! (temperature).It is like having the broiler on under the covers. After about a 1/2 hour she has to stick her head out as she is to warm and panting. I will have to take a temp reading to see what the difference is.
My Meatball Kody is a a little heatrock...he sleeps under the covers with us and rotates throughout the night...in and out without disturbing us. He is creative when getting back under the sheets after he gets out.
