We have a cat that's 12 years old and he has a huge growth between his nose and mouth. I've asked my vets assistant about it and she seems to think we should leave the growth alone if its not bothering him. The growth started out and I really just thought it was a mole that just popped up. Then each week it grew in size. I'm afraid it might actually be cancer and in fear it will spread if he has surgery. Has anyone seen or had to deal with anything like this? He's always been healthy and he is an indoor/outdoor kitty.
