Our cat was attacked by a fox/coyote a few week ago and suffered deep bites on her abdomen. She has been getting regular redressing at the vet so I hadn't seen this before today. I removed her bandages today as per the vet's instructions, and wherever there is a puncture there is a bump around it that makes it look like a miniature sucker.
Is this normal?
Will they go away?

What caused them?
