Customer: Hello, my cat has been having a weird skin rash/bumps on her head and around her ears. She’s been itching her head and ears a lot, and when you look at her head it almost looks like she has dandruff because you can see little pieces of what looks like skin. Her hair is now starting to come out in tufts, it almost looks like it’s coming out directly by the root because you can see skin attached to the bottom of the tuft. Her hair loss is only from her head though at this time.
Veterinarian's Assistant: Hi there. I'll do all I can to help. When did you first notice the dandruff? Has the cat been licking or rubbing the skin?
Customer: It’s been going on for about 2 weeks or so now. Yes she has always been a cat that grooms a lot but she is doing it a lot more recently.
Veterinarian's Assistant: What's the cat's name and age?
Customer: Her name is***** don’t know her age for sure, probably at least 3 or 4
Veterinarian's Assistant: Is there anything else the Vet should know before I connect you? Rest assured that they'll be able to help you.
Customer: She has been sleeping a lot more than normal, and over the past week or so she hasn’t been eating a lot. She’s lost a bit of weight. We have to feed her wet food (she’s normally a dry food cat) and even then she’s not eating much. She also has been hiding under the bed and yesterday she even peed down there, she’s normally pretty good at using the litter box
