I did a google search and came up with lists that only show veggies that are high in fibre. Someone suggested that I give Harley more fibre in his diet. But I'm having trouble figuring out what raw meats are naturally so. Any input would help, thanks~
There is no fiber in meat. That's why I suggested pumpkin, metamucil or slippery elm. Cats don't necessarily need a lot of fiber, but since he's having anal gland issues, bulking up his stool a little bit may help. But have you taken him to the vet yet? You really need to start there and ensure he doesn't have an infection.
In the recipe section of catnutrition.org (which is a site endorsed by Lisa Pierson of catinfo.org) they include an option to include fiber in their food recipe and state the following:
**Not all cats require additional fiber (psyllium) in their diet. If your cat has been eating low-quality commercial food for several years, especially dry food, she may have lost bowel elasticity and may benefit from the extra fiber. As a general rule, I recommend using psyllium when an adult cat first gets raw food. I rarely add much psyllium to my adult cats' diet. Bear in mind that some cats seem to get constipated without additional fiber, whereas other cats seem to get constipated if they get too much fiber. Each cat is unique, and you'll have to judge what works best for your cat.
Ah well, since the authorities don't necessarily agree, then the operative message that "everyone needs to judge what works best for their cat" still stands. For people who don't take a purist approach a little veggie fiber certainly won't hurt and it may help.
