My cat , Trumpet had a surgery last week , removing her uterus. She got sick and sent her to the vet but they didn't know whats wrong with her . They did lots of tests and finally it's confirmed that her uterus is having infection so they have to spay her.
The vet also says if you don't plan to breed your pets , it's best to neuter / spay them because they will be healthier and live longer.
Just thank god that it wasn't virus or something. She is recovering well after the surgery , now she keeps wanting me to pat and scratvh her body <3
