The litter of kittens that the stray cat on my farm had is doing so well, and getting so big. They are walking and they know me when I go into the garage to see them, it's almost like they are excited to see me. The runt of the litter...of course my favorite one has developed this lump on her face. It's on the right cheek and she has no whiskers or hair there just this lump and this black thing that looks like a scab by her nose. Any ideas on what it could be?
