Mishi is my personal warmer -- he always feels more warm than Mitzi. The vet checked him and his temp is normal (around 102 F.) -- he's just one hot kitty! His fur is that silky, soft Maine Coon long stuff - maybe that's why the body heat can be felt through that wonderful silky soft fur. Mitzi has a very thick wooly coat (heavy fur? ) so it's difficult to tell her body temp through that.
