My little Gemma is just 3 lbs too and she is often very cold too! I have a heated pet bed for the girls in the kitchen and I love love love it! They weight of their body warms it up when they lay on it. All 3 can fit it together too
At night they sleep with us so I don't think they are cold at all. She always "spoons" me!! Haha its hilarious! Plus I put the electric blanket on for my side too....
I would highly recommend the heated bed!!
