Here's the list of supplements. On second thought, I'm not sure there's anything here that may help CJ. If she has any inflammation, Slippery Elm Bark might help (see below for explanation). They're all flavorless except for S. Boulardii, which can taste bitter to some cats, so I don't think they'd replace Fortiflora in terms of getting Bonnie to eat S&C. Will she eat another flavor besides Duck Duck Goose? Or another brand of duck wet food? I have to use Fortiflora to get Marsh to eat DDG as well.
I put this list together based on things I've read on IBDKitties.net, on the IBD Kitties Facebook page, and on other online research. I didn't get any of this info from my vet, but it's all based on holistic vet approaches. Different cats might not need all (or any) of the below, but since our kitties are so individual, who knows what might work for each of them. From what I've read, you should be able to give CJ the digestive enzymes (if you want to give them to Bonnie and they share food bowls) and it shouldn't hurt her. But since she has a history of lymphoma and who knows what might trigger it again, I'd double check with the vet before giving her something new.
I'm not giving ALL of the below to Marshmallow but I did a bunch of research to try find out what I can do for her without pumping her full of drugs. I'm starting with the digestive enzymes, then I'll add probiotics (Renew Life Ultimate Flora (15 billion CFU), ½ capsule, twice daily). It has lactobacillus and bifidobacterium. She alternates between constipation and diarrhea which indicates a tug-of-war between issues in the intestines and issues in the colon so hopefully that combo will help her.
Good luck, and hopefully something on this list will be helpful for one of your kitties!
Digestive enzymes help kitty digest the food so they use more of the nutrients in the food. Start small, and work up to the recommended daily dose on the bottle (best if divided into however many meals you feed and added to the food at each meal time). You will want to make sure none of the ingredients bother her, so start with digestive enzymes and after kitty is up to the full dose and tolerating it well, then maybe add probiotics if they sound beneficial for your kitty. You will know if kitty is tolerating it if there is no vomiting, no mucous in the stool, or anything else that indicates it’s upsetting kitty’s system. If she tolerates and does well on those -- and you should know inside of two weeks -- you should see smaller stool, slightly harder, but not constipated. Less volume of stool means she’s using more of the nutrients in it. (I use Animal Essentials Plant Enzymes and Probiotics and I've definitely noticed that Marshmallow feels better on it. Fortiflora is a good taste enhancer, but it didn't change how she felt or behaved.)
Probiotics
S. boulardii is a yeast-based probiotic that does not colonize the gut. It helps displace unhealthy bacteria, promote growth of healthy bacteria, and helps normalize intestinal function. It has anti-inflammatory properties, and passes through undigested and works locally in the lumen of the gut. If you stop using it, it will be completely out of the cat’s system within 36 hours. It is more beneficial when diarrhea is the problem. It can taste bitter to some cats, so you might have to put some in a capsule and give it to kitty in pill form. Some cats will take it mixed with water in a syringe.
The other probiotics are bacterial and help colonize the gut with healthy flora.
Lactobacillus acts in the intestines (which tend to be responsible for vomiting and constipation) and
bifidobacterium in the colon (which is usually responsible for diarrhea).
Acidophilus helps amino acid uptake and utilization of B12. All of the above can be mixed into wet food at each meal and are flavorless.

Some of the brands on this link indicate which probiotic strains are included. You will have to look up some of the brands to see which probiotics they contain.
Supplement
Slippery elm bark is like a "liquid band aid." It helps coat and soothe the lining of the GI tract, like a kitty version of Pepto (never use human Pepto Bismol or Kaopectate on a cat). It can help with inflammation in some cats (not just with IBD inflammation, but also with urinary inflammation and other kinds as well; see the link to LittleBigCat.com for more info). Mix about 1/4 teaspoon of slippery elm bark powder with hot water for every 10 pounds of body weight, or take a tablespoon of hot water and mix it with about 1/2 capsule of SEB powder. Mix well and put into a syringe. Make sure it's not too hot before giving it to kitty. As it starts to cool, it will thicken. You may need to add either more powder or water to get it to a thin enough consistency that you can fill a syringe. Use a 3ml syringe, and fill completely. It has a slightly sweet flavor and is usually well tolerated by cats.
Slippery elm bark should be given at least two hours away from any other medications or supplements to allow the digestive tract to let absorption take place, mostly in the intestines. Some holistic vets believe that when given with a meal, it can inhibit the absorption of nutrients from the food. Here is the SEB brand recommended on IBDKitties.net:
Celebration Herbals Slippery Elm Bark Powder Bulk Tea Caffeine Free. For more information on SEB:
