Cha-san Got Too Hot

Recently, it has been really cold , windy, rainy and wet at night so mama-san turns the heat-dish higher than usual.
Cha-san likes the heater and comes out from his room when mama-san turns it on.
He seems so relaxed and cozy when he gets warmth.
However, he got too hot after a while so he got off the couch and was zoning out as if he took a long hot bath.
He went to drink water, came back behind the heater, and laid down.?

mama-san keeps the heater lower since then.
Such a luxury winter experience for Cha-san?
