Help my Maisy Daisy while she’s in the ER vet

Hello guys, my cat has been waiting for a cystotomy that’s on Monday, unfortunately Maisy Daisy has acute kidney poisoning/damage while she was waiting. She’s hospitalized at the emergency vet. She is getting a bunch of medicines and liquids, but unfortunately they told me it’s not guaranteed that it’ll make her better. To make it worse this was all during my birthday :(. I could tell she was fighting very hard while I was heading to the vet, please wish my baby good luck on her journey. Please spread this around it’d mean a lot. UPDATE: got a call today and got told she is responding to the treatment:) first good news of the day.
