I've noticed a scab on my almost a year old cat. I have two, but only one of them gets those scabs, they're both indoors and only go outside in a harness in our garden. We recently moved and ever since then she's been getting those scabs but they go away within a week or two, but this one is different then the others she had! I'm clueless as to what it could be, as both my cats don't have fleas or ticks and when they do have ticks they're removed instantly. Thank you for the help!!
