Pet's info: Cat | Persian | Male | unneutered | 1 year and 2 months old | 8 lbs

My cat is just a little over 1 years old and I just noticed he has two lumps on his stomach. One on each side alost on the inside of his legs type area. They don’t seem to bother him but since I found these I’ve also noticed he’s been losing chunks of fur.

Thanks for using Petco Pet Education Center, formerly Petcoach! An examination would really help to better characterize them. This could be benign or malignant growths. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
