NEED HELP FOR PAISLEY

Paisley is a tiny little girl who has been in foster care to gain weight she has been a little fighter since her arrival. Yesterday bright vibrant Paisley was not her typical kitten self she was brought into our vet. Upon her examination she had a 106.6 temp we immediately had her rushed to the nearby emergency vet. Currently her temp is only down to 105 they are unsure of the cause and have her on IV fluids and antibiotics. She is in isolation as the fever is unknown origin. They are estimating our bill to be upwards of 4000.00 or more depending on how long she needs to stay. We will do anything to help our little girl and we know she can pull through given the time and resourses
Please help us help her.... she is the sweetest little kitten who loves to play and snuggle she deserves a chance to get well and eventually find her forever home
