Mast Cell Tumors in Ferrets


These tumors are common and are mostly benign.

Look out for strange lumps on your ferret which come in any of the following shapes

Small, flat tumors
Tan in color
Crusty, like a scab

They are usually found on the head and body but can also be on the tail, toes or eyelids, causing redness and itching. If scratched, the tumor could bleed.

If you notice anything resembling a mast cell tumor on your ferret, take it to your vet for removal.

  1. Thanks so much for alerting me to that, Alvar! I’ve deleted the link.
    I checked Google quickly and couldn’t find the same article by Bruce Williams so will have another look when I have more time.

  2. Alvar … I found a pdf by Bruce Williams which has information about Mast Cell Tumors which I’ve added to this page. It’s there for you to download if you wish ?
