My cat has vaginal discharge. Is it normal or a serious issue?

My cat has this really thick discharge from her vagina. It's mostly clearish with a little yellow. She was treated with clavamox a week ago for an unknown infection. Could this just be her going into heat? She licked it off and I haven't seen much since, I just didn't know if this discharge was normal or not

Cats don't normally have discharge even when they are in heat. I would be concerned about a condition called pyometra. This is a major infection in the uterus and requires a spay procedure to remove the infected uterus. I would recommend taking her back to the vet for evaluation. It may be necessary to do blood work and abdominal x-rays to diagnose if she has a pyometra. That may be the source of the unknown infection for which she was recently treated.

It is probably pyometra, if you can see the discharge it is usually an open pyometra which means it is less urgent (but still is quite urgent), she needs to be taken to the vet today and will probably need to have her uterus removed ASAP.

A pyometra doesn't happen when they are in heat. It typically happens a few weeks after the heat cycle has ended. So, I doubt that is the problem. Some vaginal discharge when they are in heat is normal and the amount can vary from queen to queen. There is no "normal" amount I can give you. All I can say about that is that the discharge should not be enough that she is leaving puddle around. Hope this helps. Best wishes!

Cats do not typically have a discharge during their heat cycle, and in the picture you provided, I'm concerned the discharge looks like pus. This can signify that Tyga has a pyometra, which is an infection of the uterus. I'd take her into a vet immediately to get this checked out as if she does have a pyometra, it is fatal without treatment. I hope this helps!
