Hi all, i have recently noticed a couple of small sores on one of my central's belly,s to tail area. But today i noticed there is a lot more and the other one now has a few too. They are only the size of a pin head, not open just look like the scale is swollen and yellow in colour. I am takin to the vet on mon but am just seeing if any ones knowes what this is or how to treat it? Any help with what could have coursed it or how to treat it would be much great, thanks!
