Hi. My cat just developed a lump on his head. I attached three photos. Any idea what that might be? Thanks?

It’s hard to be sure what this is from the photo. The most common lump that come up quickly in cats is an abscess, or pocket of infection. They develop from a puncture wound usually. If it’s an infection it will be sore, hot to the touch, and feel soft. Due to Sampson’s age though this could be a mass or tumor. Those lumps are firm, non painful and do not feel warm. I recommend a veterinary exam to determine what the lump is. They can take a needle and examine some cells from inside the lump and get a diagnosis. If it’s an infection this should heal with antibiotics. If it’s a growth, depending on the diagnosis they may just watch it for enlargement or recommend surgical removal. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Samson.
