I like to lay on my side in bed and read, and my cat will snuggle up in front of me. Often I’ll later flip around, and we’ll have each others’ back.

I tend to flip around a lot before falling asleep, so she’ll usually go lay at my feet (preferably on my blanket), but she’s good as long as she’s close.

Don’t cats have a protective instinct as well, where they face away from one while being comfy together?

I found this on it; still need to read through it. Some sort of lithium battery technology, it seems.
