Our new vets vacinate the pets now in the thigh, leg so
If they get that type of cancer they can take a leg off to get rid of this aggressive cancer. ours was where she had had some fluids saline given to her when she was sick and dehydrated.

I guess it is more common then is ever talked about. Because it was my husbands cat hattie was very active still though the wound/cancer kept growing. Hubby insisted that we do dressing changes. The cancer had spread to cover half of her back, finally he let me put her down, it was an awful time because jeffs mother past away at this time. He dug a hole and i took her in then brought her home and jeff burried her.WE flew out the next day to help make arrangements. I have posted about this before but she died of myosthinius gravise MG. It is an awful disease.
We now have 3 cats buried in the back yard and 3 living in the house. We don't let them get out side though 2 of them try to get out.
