Hi, I recently adopted a 2 1/2 year old rabbit named Winston. I have had him for about two months. Today I noticed a growth on the top of his foot. I have not noticed it before, and I clipped his nails last week and did not see it so I think it has come in the last week. He stays on carpet most of the time and does have a litter box with a screen. Nothing is wrong with the bottom of any of his feet. The growth is about half the size of a dime, it is pink and squishy, not hard. I had him neutered about two weeks ago and he was checked out by the vet at that time. I don't know if I need to take him in to get this looked at, or if it will go away. Has anyone experienced this or know what it is? I can take him to the vet if necessary, but it doesn't seem to be causing him pain. It is concerning though. I tried to attach a picture. Please let me know
