heated cat bed/mats

[paneer]

Are they any good?

Wondering about this.

That looks quite good. I allow Seniorboy an electric blanket because with his old joints, he likes to lie long and not curl up - but they certainly all love heat.

like a proper electric blanket?

Well yes - but my household layout permits that. (He has an electric blanket left on, on the bed, duvet over it, and a fleece throw on the very top - so that he can sleep between that and the duvet, or between the duvet and the blanket depending on how hot he wants to be.) It's not always practicable for most people - or even desirable, perhaps. Just suits him us.

I want to be your cat

They are super....as long as you accept that your cat is still likely to sleep in your bed, or on the comfiest chair.
