Little Copper has been limping for a week. I thought maybe a sprain, but I saw he was getting sicker all the time. I took him today and it was an infection in his leg from a small wound that we did not see. They cut the fur on his leg to look at it. Maybe a scuffle with another cat. He is now on antibiotics and will be feeling better a few days. So glad because I was getting really worried about him.
