I've never heard of it. I wonder what happened to her cat. She posted the question, then disappeared.

That is scary. But I agree with the person that responded to her. Tak your cat to the vet! Don't ask on a forum!

Thanks, Sofia.  I was just coming back to post here.  Okay, so the red color of the product is normal.  That's good to know.  Hope that posters cats are okay.

Oh oh. I bought a couple of cans a few months ago and my boys gobbled it up like crazy - especially my kibble-freak cat. Figured tuna-only as an occasional treat would not be so bad, but did notice Mr kibble-freak wasn't dealing well with so much rich tuna gobbled so fast (barfed red tuna does not do much for a navy blue carpet either), Didn't realize it was tied to Castleberry. Now they will not get the other can.  
I've seen other BB/Castl products that were not ok, had a bulging can of (people) sardines once awhile ago-called the code into the company- they didn't even have the courtesy to have enough staff to answer phones- for complaints there was a "leave your name and number" and we "will get back to you". Ya -  right. I just left the code info and hung up. With food for pets or humans, companies just don't care. Kitties and me will take our fishie business elsewhere.
