About Vetoquinol Pro-Pectalin

Help Firm Up Stool Fast

The combination of stool-firming ingredients in Pro-Pectalin can be used at the first sign of a loose stool.

Pro-Pectalin is:

  • Formulated with pets in mind: No guessing which ingredients are pet-safe.
  • An all-in-one product: Makes administration easy and accurate.
  • A combined approach: Probiotics alone may take weeks to re-establish the microflora balance, so Pro-Pectalin includes ingredients that bind to bacterial waste and firm stools, as well as probiotics.

An All-in-One Remedy for Loose Stools

Formulated to help maintain gut microbial balance and intestinal health, Pro-Pectalin supports normal digestive function, fighting loose stools caused by:

  • Eating table scraps
  • Stress
  • Dietary changes
  • Garbage gut
  • Antibiotics

Easy to Use

Comes in an oral paste or chewable tablet form for easy administration.

Fast Acting

Starts working within 24-48 hours, for much faster relief than probiotics alone.

2 Tasty Flavors

Choose from artificial beef-flavored chewable tablets or chicken-flavored oral paste.

3 Trusted Ingredients

Made with intestine-soothing kaolin, pectin to absorb water and firm stool, and the probiotic Enterococcus faecium.

Too thick to use

This medicine is impossibly thick and extremely difficult to squeeze the plunger. I don't think anyone would be able to administer this by themself without the help

This medicine is impossibly thick and extremely difficult to squeeze the plunger. I don't think anyone would be able to administer this by themself without the help of someone else. The medicine itself is so sticky and viscous that it doesn't cut off itself when you stop squeezing, and the whole glob pulls out of the cats mouth when you pull the syringe away. It needs to be thinned out or find a way to package in individual doses that are easier to squeeze.

I’ve been using this product for years since I had my dog. I now have a kitten along with other cats and I’ve used it anytime.They’ve had an upset tummy issue. I only gave this four stars because my vet told me do not use this anymore and I don’t understandwhy. He’s saying it has ingredients that could hurt them, but I don’t see that to be true but I’m not a vet. But it has worked every time I’ve used it.

I was very worried about my kitten having bad diarrhea. I knew it wasn't any virus or bacteria as he was still pretty active and in good shape. I was juat worried he was gping to dehydrate due to the bad diarrhea, plus all the mess everywhere and all over him. 3 daya of thia treatment and he was back to normal. I was so happy that he was doing good and I didn't have to clean all the mess. Great product!

No relief

My elder cat has had diarrhea for months. 2 trips to the vet and cleared, sensitive skin and stomach food, and this supplement and still squirting. Vet said perhaps

My elder cat has had diarrhea for months. 2 trips to the vet and cleared, sensitive skin and stomach food, and this supplement and still squirting. Vet said perhaps it’s IBS? I don’t know and not sure it’s a problem with the product, I’m just saying it doesn’t work for whatever is causing my sweet senior kitty to be sick.

This is the first time I've been able to purchase Pro Pectalin without a prescription. Thank you! Our dog has inflammatory bowel disease and this product stops his diarrhea immediately. Ask your vet about it for dogs with tummy troubles.

Did not help with diarrhea

The indoor/outdoor cat we care for did not like the taste and actively avoided eating this except when mixed into wet food. It did not help her diarrhea.
