Just some info about Cat food with Fish

r. Lisa Pierson has this to say about fish:
"Fish and beef are fairly common food allergens in the cat and can cause inflammatory bowel disease and skin allergies.
Fish is also more apt to be contaminated with heavy metals and PBDEs. PBDEs are fire retardant chemicals that have a possible link to hyperthyroidism.
Because fish is so palatable to most cats, many cat foods do contain some fish so be careful to read the labels.
Dr. Pierson recommends avoiding fish altogether.Fish-based cat food can contain
fire-retardant chemicals linked to feline hyperthyroidism. There’s mercury in fish, and it also tends to be high in phosphorus. So there are a lot of reasons to stay away from fish.
Ravan has Kidney disease. I bought some Pro Plan Urinary Health canned food. I SHOULD have read the label! When I got home I did. Contains guar gum,carrageenan, lots of By products,salt & artificial color!!! THIS is supposed to be GOOD for a cat with Kidney disease???
I'm bringing it back & from now on I'll take a few mins to read the label before I buy the cat food. I'm also going to contact the Purinia Company & tell them what I think of their cat food!
I'm trying to go back their raw diet.
