Heated blanket to accommodate all my cats

[Tremping]

I know that heated pads exist but I have 3 cats and they'd all want it. Could I just use one made for humans or would that not be safe? Or does a pet one exist?

A 'human' may be too large and you should never use them folded.
Would one designed for a cot work?

I have two cats and a two dogs and they love my (their) heated throw. It’s 160x120. I dont use it folded, as I put in on our (their) sofa but there’s nothing in the instructions about not folding. It’s also machine washable. It’s so good I need one that I can actually use…

I have a hoomin heated throw, it goes over me and under the cat when we watch TV.
