Hmmm, well I am glad they aren't in danger of HL!
I feed a mix of raw and canned, but I think they might be just tired of eating mainly chicken for the entire year, if that's what you normally feed at every meal. The friskies must add to their variety, I'm guessing. I realize in Lisa Pierson's website, she mentions feeding rabbit, which is one of the most expensive proteins around, but you can try turkey, duck, beef, or cornish hens, etc from a butcher, too. Just do not buy anything pre-ground. Since they already eat raw, maybe you can try giving them small chunks of other protein for variety? Try googling "prey model raw", and see if that might get your kitties intrested in raw food again.
I go to my local independent store and seek out the dog section, they usually sell 2 lb chubs of various proteins. I've found that some brands are ok for felines, you just need to add some supplements to those to make it fit for a feline's diet. The clerks there are usually pretty knowledgeable about that, or they can call the manufacturer and find out for you. Buying raw for mutliple cats is definitely expensive, so I understand cost being an issue. If you have a large freezer, though, you could buy items (online sources) in larger stock and save money on shipping and items you purchase, too. I don't have a large freezer, thus I buy mainly from the local stores here.
I did think the whole kibble and raw mixing was dangerous before, but now, I'm really not so sure. (Though I still don't feed my cats dry at all.) If the treats are making one of your kitties ill, I'd start keeping a log of what you give and when she starts vomiting. It can help provide clues to what she's possibly intolerant to, and stick to treats with a single protein instead that you know is safe. Temptation treats...I think I'd avoid those, especially those with fish ingredients. It contains BHA/BHT, which are known carcinogens. It also contains corn and a bunch of grains that your cat may be sensitive or allergic to. There are better healthier treats you could use, IMO.
