AITA for refusing to pay my friend after my ferret “attacked” her $900 dress?

So I (29F) have a pet ferret Noodles. He’s super friendly and curious, and I let him free roam when I’m home. My friend Kara (28F, fake name) came over last weekend for wine night with a few of our other friends. She showed up wearing this very extra silk dress, said she had a date after and didn’t have time to change.

I told her maybe not the best outfit for a casual girls night but whatever. Well, at one point she gets up to go to the kitchen and Noodles, being the menace he is, bolts toward her and jumps up. His little claws snag the back of her dress and it tears maybe a 1/2” slit. She screams, freaks out, and runs into the bathroom sobbing.

The whole vibe died instantly. I felt bad but also like… you wore a $900 dress to drink boxed wine on my carpet with a literal ferret present??

Anyway, she sends me a Venmo request later that night for $920. apparently the dress is from some vintage designer and the repair requires specialist fabric sourcing. I declined the request. She sent it again. I declined again.

Now she’s telling everyone I’m irresponsible and letting my rodent ruin people’s things. She even told our group chat that I let Noodles drink wine (he just sniffed the glass one time???). My other friends are split. Some say I should pay at least something, others say Kara’s being dramatic.

Then today… her lawyer dad sent me a letter saying I’m liable for damages. I literally laughed out loud. Like, what judge is gonna look at me and say “yes, pay $900 because your ferret got excited about silk.”

So. AITA or is this entire thing completely unhinged?
