Questions & Answers

Can this help with cat constipation?

Answer by Chewy • Jun 09, 2024
This paste will help maintain balanced microflora levels in the gut to relieve your pet of irritating bowel issues.

how long can you keep the vetriscience fast balance paste once opened

Answer by Chewy • Aug 01, 2019
This supplement is good until the date on the label, no matter when it's opened. The expiration date is at the end of the label, it’s an eight digit number that looks like it is typed on by a typewriter. There will be a space, followed by four more numbers, these are the month and year of expiration, going to the last day of that month.

Can I give this to a 10 week old kitten?

Answer by Chewy • Dec 13, 2021
This supplement is suitable for cats and dogs of all ages.

Does this help with vomiting for cats? Also, how long do cats typically need to take this supplement for irritable bowel issues?

Answer by Chewy • Jun 22, 2018
Although, the tube helps maintain balanced microflora levels in the gut to relieve pet of irritating bowel issues, we'd recommend consulting with your vet before use.

For a non vet or technician, it wasn’t easy to figure out how to use this device. I looked it up on YouTube. Once I gave it to him he ran away and didn’t come out of his hiding corner for hours. I may have to find another way to administer this product but for now, I give him something else in a capsule that’s easy to administer.

I have purchased this product many times in the past and it is usually a cream colored gel/paste. This tube was a nasty dark brown goo that smelled bad. Was it just a bad tube? Stored incorrectly? Who knows? I know I won’t ever purchase it again. Not putting anything that looks like runny poop my dogs’ mouths! I would give it a zero stars rating if I could

no, I think that what i paid for was the fancy tube that it comes in. Didn't work and the contents looked disgusting. I needed 15cc per dose the tube only holds 35cc I am suppose to give him 3 doses a day. I would have to buy another fancy tube of the stuff. waste of money! very expensive. i suggest that you remove this product from your reputable site. Thanks, Patrice Becker

I didn't know what was causing her diarrhea. I got this and used it 1 week. It didn’t relieve her symptoms so back to the vet. Come to find out she had the"rocky mountain two step" caused by the single cell amoeba, giardia. I will use it again in the future.

We have a dog with a long standing history of GI issues that has left all of our various vets stumped; we have had to go as far as giving vet prescribed food and daily live probiotics. Sometimes, unfortunately, this isn't enough and he gets an upset stomach for whatever reason. In the past, when he has had bouts of unstoppable diarrhea and we didn't know what else to do other than fast him and then give him a bland diet for a week at a time, we felt so lost. Now, at the first sign of an upset stomach, we give him the correct dosage amount of the G.I. paste and then feed him normally and he's good to go. We always have at least two syringes on deck. Recently, he hasn't been loving the taste of it, so we either inject the syringe into his mouth, or we mix it with a tiny bit of dog-friendly peanut butter. Highly, highly recommend.
