Tora pyometra surgery

Tora is a stray cat we picked up on the street almost two years ago, I had never been a cat lover but when we decided to take Tora home with us, it was love at first sight. I had a trauma two years ago, I was struck by panic attacks and anxiety, I could not stay at home alone, since we have Tora at home instead I am more relaxed. Unfortunately now Tora has been hit by Pyometra, an infection that affects the uterus of the animal and must be operated as soon as possible, because it can lead to the death of the subject if not treated. The costs of the operation are high and economically now I can not sustain it. And I would like to return the love that Tora gave me by saving her from this infection. Thank you in advance for your help <3 hoping the best for Tora. Thank you
