So they estimated $2363 - $3927 total if she spends the night, depending on how long (24-48 hrs)!!! If she spent the night they'd do an abdominal ultrasound tomorrow also. That's basically for overnight care while she gets IV fluids!!!
So DH had me pull her out. They only charged us the $890 and sent her home with antibiotics, an appetite stimulant, and push of fluids. We'll get the labs sent to her regular vet who we'll see tomorrow (I have a message to them to possibly see her before her 2pm appt) and get the urine test done then and IV fluids there for hopefully way cheaper. We picked her up at 9pm and she already looks much better. Her eyes are bright again and she drank a bunch of water when we got home and she's walking around. Her regular vet opens in 10.5 hours so I think she'll be fine till then.
I'll update tomorrow.
