Why do cats lie next to radiators?

Their body temp is a few degrees higher than ours.  I doubt this is the whole reason, because dogs also have a higher body temp than we do.  Dogs don’t sleep with their bodies up against hot radiators for hours on end. One of my cats used to sleep on top of a very hot steam radiator in an old house. For her that radiator was like a hit of kitty Nyquil.

I ordered a heated cat bed for my 15 year old, Emma.

I was just reading some research from the 1960’s on cat sensitivity to heat. While reading, I realized I’d forgotten that sensitivity will be different depending on body location. Face more sensitive than back, most likely.  One study, a behavioral one, found that paws do have sensitivity to temperature. They could tell the difference between stimuli with as little as 1 degree celsius (1.8 degree fahrenheit).

What’s really cute is that they received pieces of fish as a reward!
