In a Hurry? Here’s Five Highly-Rated Cat Foods for Feline Constipation

Symptoms of Constipation

Constipation is a condition in which the cat finds it difficult to pass stools. Common symptoms of feline constipation include:

Straining during defecation – Cats may spend an unusually long time in the litter box, visibly straining to pass stools without success or producing very little feces.

Hard or dry feces – When your cat manages to pass stools, they may be small, hard and dry, indicating that they have been in the colon for an extended period.

Decreased frequency of bowel movements – A constipated cat may have fewer bowel movements than usual, often passing stools less than once every day or two.

Vocalizations – Your cat may call out during his attempts at defecating.

Signs of Discomfort – restlessness and a reluctant to sit may indicate discomfort arising from constipation.

Loss of appetite – A loss of appetite is often symptomatic of constipation.

Lethargy/Lack of Energy – Constipated cats may become less active and show reduced energy levels due to discomfort and because their stomachs are struggling to process backed up food.

Vomiting – In some cases, constipation can cause a cat to vomit. This sometimes happens because the strain of defecation stretches the colon.

If your cat displays ongoing constipation symptoms such as those mentioned above, you should consult your veterinarian for a proper diagnosis and treatment plan.

Causes of Constipation in Cats

Here’s a run-down of the most common causes. of constipation in cats.

Dehydration – A lack of water results in dehydration which in turn often leads to hard, dry stools that are difficult to pass.

You  can help to prevent this by providing east access to clean water throughout the day. However, take care to place the water bowl away from the litter box!

Low fiber intake – A lack of fiber in our cat’s diet may also cause constipation.

Fiber aids in promoting regular bowel movements and softening the stool. So it follows that providing a high-fiber diet will sometimes be all that’s required.

Sedentary lifestyle – Cats with low activity levels are more prone to constipation. Exercise stimulates bowel movements and supports overall digestive health.

Encouraging your cat to engage in play and physical activity regular may also be of benefit.

Hairballs – Hairballs sometimes obstruct the digestive tract, leading to constipation.

Regular grooming is therefore pretty important especially if you own a medium to long-haired breed.

Medication – Constipation is sometimes the result of medications such as antihistamines, diuretics or painkillers.

Talk to your vet if you think this might be the cause of your cat’s digestive problems.

Medical conditions – Obesity, kidney disease, arthritis and neurological or colon disorders are often behind constipation.

Regular veterinary check-ups can help detect and manage these conditions early on.

Obstructions – Foreign objects, tumours or strictures in the digestive tract can impede the passage of feces, leading to constipation.

If you suspect an obstruction, consult your veterinarian immediately.

Stress and behavioral factors – You cats may experience constipation due to stress.

This might be brought about by the introduction of new environment, a family member, a litter box aversion or changes in daily routine.

Choosing the Best Cat Food for Constipation – Things to Consider

In selecting the best cat food for constipation, you’ll want to a brand that promotes healthy digestion and regular bowel movements.

These are some of the most important things to look out for.

High Fiber Content

Cat food with a high fiber content helps to prevent and manage constipation by promoting regular bowel movements and softening the stool.

Focus on brands containing both soluble and insoluble fiber sources, such as psyllium husk, beet pulp and pumpkin.

Higher Moisture Content

Cats often have a low thirst drive, making it crucial to choose foods with higher moisture content in order to aid in hydration.

Wet or canned cat foods are generally more hydrating than dry options, supporting healthy bowel movements and thus reducing the risk of constipation.

Quality Ingredients and Protein Sources

Opt for cat foods made with high-quality, easily digestible proteins and ingredients.

This will minimize digestive stress and promote optimal nutrient absorption.

High-quality protein sources like chicken, turkey and fish can be really helpful for cats struggling with constipation.

Be sure to avoid foods with excessive fillers or artificial additives – these sometimes exacerbate digestive issues.

Grain-Free and Limited-Ingredient Options

Sensitivities and allergies to specific ingredients may contribute to constipation as well as other digestive problems.

One solution is to provide your cat with grain-free or limited-ingredient foods as a means of eliminating potential irritants or allergens.

Simple, wholesome ingredients are often the best way to go here.

Life Stage and Activity Level

You should also consider your cat’s age, activity level and overall health when selecting the best wet cat food for constipation relief.

Kittens, senior felines and those with specific health conditions may require specialized diets to meet their unique nutritional needs.

If your cat is already on a specially-formulated diet, be sure to speak with your vet before making any changes.
