My cat's shoulder wound is leaking pus. Can I clean and drain it?

Updated On September 23rd, 2025

My cat received this injury and I a currently unable to take him to a vet, There are two holes in his shoulder and when pressure is put on it leaks slightly bloody liquid pus. I am wondering if putting pressure, draining and cleaning it is a good idea? He isn't too bothered about me touching it.

Yes, this will heal more quickly if you keep it draining. You can use a hot moist compress on the area to massage out the fluid and keep a scab from forming. Do this twice daily until there isn’t fluid under the skin. After you’ve cleaned the area you can apply a thin film of antibacterial ointment on the wounds. It’s best if he doesn’t lick the area. I expect this to fully heal in a few days to a week. If the area becomes painful, he stops eating or it isn’t healing then please take him right in for an exam and treatment. He would then probably need oral antibiotics. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for your cat.
