Jenny had a benign apocrine adenoma tumor, and it was totally removed during the surgery. So all should be good with her. Providing she doesn't scratch out her stitches. Although it is very difficult to tell if she is scratching them because Maw can't get close enough to tell, and when she picks her up, Jenny puts her head down so that Maw can't see how her stitches look. Such is the life of a mostly feral kitty. It's a very good thing that Jenny has been extremely healthy all of her life until this last year when she started catching colds, and needed antibiotic shots, and then she had this tumor. In the past, it was very difficult to catch Jenny to put her in a PTU. When Maw would catch her, Jenny would pee and poo from all of her fear. So Jenny would only go to the v-e-t about every 3 or 4 years to get her shots. If Maw could catch her. Now that Jenny is not as quick, and doesn't race away from Maw, it is much easier for Maw to catch her and stick her in the PTU.
