Well, you certainly didn't prevent it.

You know what you did

So you admit that you didn't watch out for her?

Mine would also bite me for disrespect

Cats really are liquid.

I think your laughing at her fall might have had something to do with it. (I assume you laughed, I can't imagine not)

How could you do such a thing? 😾

I'm delighted this is the first thing I saw today!

My large dog would have carefully positioned himself under her to provide padding when the inevitable happened.

You're supposed to protect her, that's why she sleeps near you. Do better next time.
