Cat has pus running down back leg

my stray cat all of a sudden has pus all down her legs coming from her butt what could be wrong with her?

Answer by Kate
Pus always means an infection of some sort and if it is coming from her rear end means that it is likely that she either has a wound in that area or an internal infection. you will definitely need to take her to a vet as soon as possible to have this treated.

I hope she is better soon

best wishes kate
