My 19-year-old cat has spreading bloody paw growths. What is it?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 19 years old | 5 lbs

My 19 year old cat has a large lumpy bloody mess on one toe on her back paw. A month ago it was one, 1/2” long hard growth. In one month it has now developed 4 distinct growths. All are raw and bloody, Non movable, and hard. What could this be? How do we treat foot ie., cleaning, wrapping, medication?

I am afraid this is a serious condition. Please take Misty to your vet for a biopsy or removal of the mass, which , unfortunately , probably is a malignant tumor. While it is not possible to tell by photo whether a tumor like this is malignant or benign, experience shows that most tumors in cats are malignant. Your vet will also want to take xrays of the lungs as most masses on the paws tend to be indicative of tumors in the lungs as well. Please schedule an appointment with your vet ASAP.

    It looks like he could have an infection so he should be examined by a vet for treatment. Your vet can prescribe an antibiotic to see if it will resolve. If not, then surgery may need to be done to remove the lesion.
