First post, also on mobile. LONG POST.

So she gets us to babysit her cat for 2 weeks.

We told her that she'd have to deflea and deworm him b4 he came over, all of her animals have fleas because she usually had barn animals in her apt, she told us that she did and so kitten comes over to stay with me.

2 weeks turns into 3, then a month and then 2 months l8r and my apt is in the middle of the fleapocalypse, I'm spraying carpets, bathing cats, washing everything and I think my cat is going crazy so I take her to the vet to check for feline sensitivity and I find out that she's not crazy she just has EXTREMELY BAD FLEAS PLUS WORMS AND AN ALLERGY. My fam has 5 cats, so this kitten has infested my house with fleas when he had supposedly been DEFLEAD AND DEWORMED. So I had to fork up the $625 to get the topical deflea and topical dewormer for 5 cats.

This lady didn't abide by our agreement, my cats did not have fleas or worms prior to her kitten arriving in my apt, so I sent her the bill explaining everything and why she's being charged for it.

As expected she flips out talking about her anxiety and how much stress its causing her and that she doesn't deserve it and I'm just like okay look you can't rub some rosemary on your cat and rinse him off that's not how parasites work.

She goes on about how I should've told her b4 and how it's unfair and im like it's my cat I don't have to tell you when I'm taking her to the vet as she's not yours. I trusted you and u f*cked that up so now u get the bill. Next day she comes to get her kitten which I also bought meds for, he is looking healthier since staying with us.

She agreed to pay it but that she'd need time to come up with the money which I said ok that's fine. About a week passes without hearing from her when she texts me saying "I've talked to every1 ik and they all agree with me tht since u didn't give me a heads up on taking ur animal to the vet that I should only have to pay $320 bc I price matched the meds u got and I could've got it for that price."

I didn't want to deal with her, ik tht she sues ppl when she doesn't get her way. So I just told her yeah that's fine, it's about half of the amount so whatever. She says awesome and that she gets paid twice later that week so it shouldn't be a problem. 

Cut to now and she still hasn't paid us back. She's called when she knows I'm asleep asking to hang out, she stopped by my sisters work to try and get free water for her car, and i think I might have to let my husband handle this which I dont want to do bc he is a petty person and will get police, law suits, the whole nine yards involved.

I'm currently pregnant, a disabled veteran, current national guard member, and I lost my job in December so money is tight right now. I understand it's difficult to pull money out of the sky but I've given her plenty of time.

WIBTA if I just let my husband handle this and AITA for expecting her to pay at least half?
