I have multiple cats ranging from 2 yrs old to 4 months old. They have all been treated for fleas and tape worms and are now flea free and on last worm treatment. My question is has anyone had cats that have lumps all over them under their skin with a white center?  lump with white center on hind leg

  • Could just be skin tags. Did you ask the vet?

  • No the lumps are under their skin. Some are just a single lump and others are vein like meaning it feels like a swollen vein long and in a wavy pattern. I wonder if its their litter although I haven't change it to a different brand. Nov 15, 2016 at 9:46

  • Yes I'm sure this is his hind leg its deffinetly not a nipple Nov 15, 2016 at 18:16
  • Did you ever figure out what this was? My kitten is having the same problem
