If your cat has gallstones or inflammation of the gallbladder, it can lead to the formation of sludge in the gallbladder and bile passageways.

This may lead to a blockage that prevents the bile from moving out of the gallbladder and into the intestines as it should.

This can cause the bile to be reabsorbed back into the gallbladder and stored in the organ. When this happens, it forms a yellowish liquid called bilirubin.

What Is The Best Way To Treat Cat Diarrhea?

If your cat develops diarrhea, your veterinarian may recommend withholding food for 12 hours to help normalize its bowel movements.

In most cases of diarrhea in cats, eating or drinking should be avoided as it can result in dehydration, which is a serious condition requiring veterinary treatment.

Even though it may seem inconvenient, it’s usually a good idea to withhold food for 12 hours if your cat is experiencing diarrhea.

This will help prevent dehydration, as your pet loses more fluids in diarrhea than in vomiting. Initially, and often before a diagnosis is reached, a diet of bland foods may be used to reduce irritation and swelling of the bowel lining.

If your adult cat is otherwise healthy, your veterinarian may suggest giving mild and age appropriate over the counter medication for diarrhea for a day or two.

Owners should pay attention to their pet’s waste if it extends outside the litter box and begins to smell or appear different in color or texture, since these could be signs of another problem.
