Hi, I noticed this on my cat's rear foot last night and wanted to know what it was & if I should take him to our Vet to have it checked out. He doesn't act like it hurts when I touch it & he doesn't limp or anything. Thank you.

Anytime a new mass is noticed, I always recommend having it evalauted to see what it is and if anything needs to be done about it. Unfortunately, we can't tell anything about a mass by just looking at it. Your vet can perform a simple test called a fine needle aspirate where they use a small needle to collect some cells from the mass, then look at them under the microscope. They may even need to send the cells to the lab for a pathologist to examine them, so we know what the mass is. If it is benign, you might not need to do anything aboout the mass at all, but if they see cells that worry them, they might recommend removing the mass. Good luck! I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
