I agree with Villette! They do get cold ... since they are single-coat and don't have an undercoat to keep them warm. Toto snuggles against us when she is cold and if she gets too warm, she will move away and "sprawl" all over the place!!
I make sure that she has a bed in different rooms in case she wants to lie on the floor and she has a little sleeping bag on the sofa. If you leave little things around for them ... and they get chilly, they will find something to snuggle up in!
