Hello!
Congradulations on your cat of the day. We went through the same thing with our cat Zella. We made the mistake of letting our vet give her the steriod shot for her allegies which they said was food related. And for about a month it was like we lost her. She was like a zombie and it was heartbreaking. If tulip is allergic to her cat food try Trader Joes Holistic cat food. It completly saved our cat. Since we started her on that she has not got any rashes and her fur has become glowing. Our vet recommended science diet anti allergy cat food. Turns out the only thing she was allergic to was that cat food. Remember the Vets are in a business and shots and special food mean profits.
