Dr. Marie Menniti's Veterinary Advice

All cats will leave a stinky litter box on occasion. It can, of course, start to get bothersome if it becomes a regular occurrence.

Thankfully, smelly poos aren’t necessarily a sign for concern on their own. 

If they are accompanied by other clinical signs, however, your cat may need to see a veterinarian.

Here are some tips to choose a diet for a cat with smelly poos.

1) Choose a diet that contains prebiotic ingredients

Prebiotics are ingredients in the diet which feed the healthy bacteria of the gut. Examples of prebiotic-containing ingredients include cranberries, apples, and carrots.

Remember that these ingredients have been incorporated into the diet in a balanced way- don’t simply add them to your cat’s diet without checking with a veterinarian.

2) Choose a diet that has a source of insoluble fiber

One type of fiber, called “insoluble fiber”, will help keep things moving in the gut. It increases fecal bulk and speeds up movement of food through the gut. Examples of insoluble fiber sources include pea fiber, soybean hulls, beet pulp, and rice hulls.

3) Choose a diet that has a lower total crude fiber content

In general, as the crude fiber content of a diet increases, the digestibility decreases. A highly digestible food will allow for more of the nutrients to be absorbed in the gut with less waste to come out the other end. That can certainly be of benefit to a cat with smelly poos who may be able to visit the litter box less frequently!

4) Try a hydrolyzed or single-protein diet

Some cats may get a gut upset when they eat certain ingredients, leading to a smellier litter box.  If you suspect your cat has an allergy or sensitivity, choose a food that uses a protein source they have not eaten previously. The best choice, however, is to use a hydrolyzed protein diet.

These diets use proteins that are broken down into smaller pieces that are unlikely to trigger a reaction but will still provide all the amino acids that your cat needs from the diet.

5) Don’t change diet too quickly or too frequently

When you are choosing a food for your cat, one important thing to keep in mind is to not switch diets too quickly or frequently. The gut of a cat and healthy gut bacteria need time to adjust to changes in composition and texture of new foods.

The transition should happen over a minimum of 7 days, increasing the proportion of the new food in the bowl each day.

6) Consider the energy needs of your cat

Obesity can have an impact on gastrointestinal health in cats. If your vet advises that your cat is overweight, you might want to find a less ‘calorie dense’ diet to help her slim down.

Your veterinarian can help you determine how much to feed each day for your cat to meet her ideal bodyweight. You should measure out your cat’s daily portion using a scale, as cups are inaccurate.
