Thank you for contacting Doctors Foster and Smith with your question regarding the Glandex Anal Gland Fiber Supplement.
If your veterinarian has not been able to find an underlying cause, but the stools improve with the addition of fiber to the diet, that is considered fiber-responsive diarrhea. If your cat’s stools improve with pumpkin (which is basically fiber), this product may also improve your cat’s stools since it contains fiber.
We would recommend discussing this with your veterinarian before making the switch to be sure that this product is deemed appropriate for your pet.
We hope this information is helpful. Thanks again for contacting us.
Drs. Foster & Smith
