Aaaaaaaaw, poor Ollie, you cruel mummy!

Why not put him one of those heat pads under his cat bed - he will like that I'm sure. I mean those for muscular aches and pains - 2 in a box for 99p at Wikinsons - 1 lasts up to 24 hrs. It will do instead of the digi box!!! You will have to make sure it's not ripped apart though as it could be bad for puddies.
Good luck with getting a warm spot Ollie.
