Yes what I read for hyperthyroidism was because of the BPA, I just remembered. This information is quite easy to have so I'll check with different food companies!Yes, it could well be the legumes -- some cats do have difficulty with that. (As do some humans... lentils and chickpeas, in particular, can cause flatulence!)
Another twist is that even though a food is hypoallergenic, that doesn't necessarily that a cat won't be sensitive to it s o even the hypoallergenic Petcurean could be a problem. Negative reactions to foods can be similar even when the causes are different. Here's an article that explains a bit about allergies and intolerances. I saw another good one recently (about allergies and sensitivities) and can see if I can dig that one up, too, if you want!
I bet what you saw about the link to wet food and hyperthyroidism concerned BPA, which can be in the can coating, right? That's definitely something to watch out for; fortunately, a fair number of companies have eliminated it from their cans. Fish can also contribute to thyroid disease.
I hope some wet food might help out. Do you need suggestions or do you already have ideas on what to feed? Are you in North America? (I think so based on the brands you mentioned!) Also, what is your cat's name?
I have yet to see Ziwi peak anywhere but online!This is how much I know about Ziwipeak:
It is a New Zealand company.
They have very few flavors.
All animals are grass-fred or wild caught.
They stopped using carrageenan by popular demand.
You can't find it at any big box pet store or grocery.
Yes, they say: we use chickpea as a natural binder for the high meat content ingredients.Ziwi Peak generally has a good reputation but watch out because many (most? all? I'm not sure) of their foods have chickpeas. If I'm not mistaken (and I could be!) they added it to thicken the food, replacing the carrageenan they removed, as Daisy6 mentioned.
They sell it at one or two of the independent stores near me. Yes, it's pretty expensive!I have yet to see Ziwi peak anywhere but online!
It looks like a great product but unfortunately out of our price range =(
Yes, absolutely!Yes, they say: we use chickpea as a natural binder for the high meat content ingredients.
But to keep it in context, over are 95% fresh meat, organs, bone and seafood so when used as a thickener rather than a 'filler', it's a minimal amount.
I buy this food, but not constantly as it is expensive.
I've known a handful of folks who feed Ziwi and I've never heard anything but rave reviews!!!They sell it at one or two of the independent stores near me. Yes, it's pretty expensive!
Yes, absolutely!
TOTW gave one of our cats screaming diarrhea with anal gland problems as a final thought..Ziwipeak gives one of my cats diarrhea
