an Allergy story

Alright so once upon a time Skunk was vomiting alot and so I got worried and took him to the vet, apparently he's allergic to "Red dye #3" which is common in basic cat foods out there in the world. Since then of course I've taken to reading the back of the bags to catch for this ingredient...makes me really feel like a parent

Anyone else have cats with this allergy? Your not alone, Skunk understands! ^_^

I just found out my Oreo is allergic.
She was put on Hills D/D.
My Coco is allergic also and also has asthma.
She once had fur fall out in clumps.
Funny thing is both of them are black and white.
I know they are not allergic because they and black and white.
