Save my best friend

Hello my name is Amina and I’ve had my baby Gypsy since I was in the 11th grade. Gypsy has grown up with me so much over the years from move across the country twice, to surviving a whole pandemic. She has always been there for me and now it’s my turn to really be here for her. Late last night Gypsy collapsed out of no where and became unresponsive. Upon bringing her to the vet I found out Gypsy has infection in her uterus that has put her in a life or death situation. Please help me save my best friend, I can’t imagine a world without her.
