I'm giving away my cat and having second thoughts

Can you keep him? Poor Bertram.

“Stealing their breath”? How does that work, exactly?

Snopes has this to say on the subject.

I’ve woken up many a winter’s night with the cat draped over my face (presumably for the warmth) and even with my allergies, I’m still here. The cat isn’t, but that was natural causes.

Sounds like SIL wanted it to be the cat’s fault rather than her kid’s fault. Some people can be odd like that.

Argh! Sorry to hear this! SIL is an idiot.

It’s never easy to say goodbye but sometimes it IS necessary.

Your sadness will be of great comfort to some one else, so that in itself, is something to find comfort in
