If you notice your cat seems to be spending a lot of time in the litter box without a lot to show for their efforts, they could be suffering from constipation. The condition occurs when poop builds up inside your cat and becomes hard and dry, making it difficult to pass normally.

Dehydration, hairballs, and foreign body ingestion are often to blame if your cat becomes constipated. To treat and prevent constipation, your vet may suggest using a cat laxative. To help you choose the right product, we’ve gathered reviews of what we think are the eight best cat laxatives to try this year. As always, rely on your veterinarian’s advice to help you make your final choice.

  • The 8 Best Cat Laxatives

    1. Lactulose Generic Oral Solution – Best Overall

    Lactulose Oral Solution

    Product form: Liquid
    Size: 16 oz or 32 oz bottle

    Our choice for the best overall cat laxative is Lactulose Generic Oral Solution. It’s designed for regular use as a stool softener and is commonly suggested and prescribed by veterinarians. Depending on where you purchase Lactulose, you may need a prescription from your vet. Since it’s available in a sweet-tasting liquid, Lactulose can be mixed into food or administered directly by mouth.

    If your cat isn’t cooperative for taking medications by mouth, Lactulose may not be the best choice because it is so sticky. You, your cat, and your house may need a good cleaning when you’re done. It should be used with caution in diabetic cats.

    Pros
    • Formulated as a stool softener and laxative
    • Available in a large bottle
    • Frequently prescribed by veterinarians
    • Can be mixed in food or given by mouth
    Cons
    • May require a prescription
    • Very sticky
    • Use with caution in diabetic cats

    2. Vetoquinol Laxatone Gel Supplement – Best Value

    Vetoquinol Laxatone Oral Lubricant Gel for Cats

    Product form: Gel
    Size: 5 oz or 4.5 oz tube

    Our pick for the best cat laxative for the money is the Vetoquinol Laxatone Tuna-Flavored Gel Hairball Control Supplement. This tasty gel is available in a value-sized 4.5-oz tube and is gentle and easy to use. Your cat can lick the Laxatone off a spoon or your finger.

    It can also be mixed in food or placed on the cat’s nose or paw to be licked off. Laxatone is designed as a hairball remedy but also supports normal digestion. Plus, as we learned, hairballs are often the cause of constipation.

    Most users report that their cats enjoy the product’s taste, making it less stressful to administer. Some found the texture slightly runny and messy. If your cat has chronic constipation, Laxatone may not be strong enough to get things moving.

    Pros
    • Can be administered in several ways
    • Also helps prevent and treat hairballs
    • Most cats like the taste
    Cons
    • May not be effective for chronic constipation
    • Messy, runny texture

Some customers warned that their cats don’t like the taste if you give it directly. However, most users reported that Pet Wellbeing seemed to help their cats maintain soft stools. It is one of the higher-priced products on our list, but it is available in either a 2-oz or 4-oz bottle.

    Pros
    • Can be used in cats and dogs

Most owners reported their cats enjoyed the cod liver oil taste of the Lax-Aire. You can mix the laxative into food or let your cat lick it off their nose or paw.

    Buyer’s Guide: Choosing the Best Cat Laxative

    Before you make your final decision regarding the best cat laxative for you, here are some additional points to consider.

    What Does Your Vet Say?

    Constipation is a medical condition that should be managed with the help of your veterinarian. It can also be a side effect or sign of more complicated health concerns. Don’t buy a laxative and start treating your cat without talking to your veterinarian first. Your cat may need testing to rule out other conditions before determining that a laxative is needed. If your vet recomends a laxative, one of the choices on our list may be appropriate.

    What Form Is the Easiest to Give?

    As you can see, cat laxatives are available in a variety of forms, from gels to dissolvable tablets. One of the simplest ways to choose which laxative is best for you is to decide which form will be the easiest to give. If your cat loves treats, a tasty gel formula may be the right choice. Picky cats may prefer the odorless, tasteless pills.

    Other Pets at Home?

    If you have other pets at home besides cats, you may prefer to choose one of the laxatives that works for dogs, too. They may be more convenient for you and cost-effective in the long run. Just remember to check with your vet first if your cat’s canine friend also suddenly has trouble pooping.
