Emergency Surgery for Beloved Cat's Survival

This is my 9 year old cat who just got diagnosed with pyometra and needs emergency surgery, her uterus is infected and is completely closed. Her uterus is bound to rupture and if it does it can be extremely fatal and lead to rapid decline. My cat has been in my family since 2016 and my husband and I took her with us so she’s fully our responsibility and I cannot imagine losing her at not even 10 years old, she was such a normal, active and happy cat and my heart is absolutely shattered at how sudden this was. Anything would be appreciated for the vet bill of $4,500 to make this surgery possible as soon as possible. I appreciate anyone who took the time to read this because if you know me you’d know I’d never do this but I don’t want to lose my only baby
