Q. My cat had a pink bubble shape coming up through his fur about 2 inches back from tail base.it burst.no oder..brown tag of skin hanging firmly on. Do?
A. I would get this seen by your vet as soon as possible. He may need to have that area cleaned up and sutured closed or at least trimmed back so it can heal more completely. In the meantime, wash it gently with a mild antibacterial soap and water and apply an antibacterial ointment, such as Neosporin, that does not contain steroids like hydrocortisone, these will slow healing. Keep it clean until your vet can see it.
