Hi all. For the past 4 or so months Mimi has required a lot more maintenance as she has a urine scald that isn't really improving. She is older now and has always peed wherever she lies down - even with bedding change every day she has a bad habit of peeing and just sitting in it. Her previous owners who had her until she was three years old didn't litter train, and I've tried and tried but she simply will not be trained. Anyway, her scald is sort of around the vulva as well as on her back legs. I clean her with a very watered down hibitane/water mixture, dry with cotton balls, and apply a hibitane/hydrocortisone cream prescribed by the vet. The vet says it's going to be more maintenance of the scald than a full recovery, at least for the time being. Recently when I was cleaning her I noticed some spots of the scald on the back of her legs has turned a dark red or purple color. I don't know what this means and I'm really worried. The soonest I can get her to the vet is Friday of this week, I'm hoping it's nothing serious. Does anyone have any idea what the purple or red blotches could mean? Does it require a more urgent vet visit? I'm sure I could arrange something sooner if needed. Also if you have any tips about maintaining scald that would be great. I've heard corn starch is good to put on the scald and surrounding fur after cleanings, but is it really bun-safe? Thanks.
