Very sticky

I give this to our girl who has Mega colon. I love that it’s unflavored and I can mix it in her canned food, because it’s impossible to get her to take it orally

I give this to our girl who has Mega colon. I love that it’s unflavored and I can mix it in her canned food, because it’s impossible to get her to take it orally from syringe. It’s extremely sticky.

I’d been purchasing Lacutulose from my vet as my cat has an illness where he will need to take this the rest of his life. I thought I could save money by buying the generic product in bulk but as soon as I’d give it to him he be would throw up. This stopped as soon as I went back to the expensive small bottle from the vet. Chewy was fantastic as always and issued a refund. I will continue to use them for many other products but probably not prescriptions.

This is precisely the medication I was getting from my vet, which has worked wonders for my cat's digestion/constipation. But the price is so much better and as her office is only open 3 days a week, it's great to have it auto delivered. Chewy does it again!

Snow related delay. It is understandable about the weather but my cat depends on this medication for health

excited chewy has this

love the large size - I have a stoppered bottle so I just use this to refill that one, but I could see how it would be difficult for someone to use this without

Quick shipping

I always receive this medication quickly and on time. My 2 liver dogs with liver shunt have to have this medication to live, so it's super important!

Same product as from the veterinarians office for so much cheaper

Product works well but unfortunately my kitty went from being constipated to having a UTI so had to get antibiotics for that problem.

appreciated getting a larger quantity and fast

My local pharamcy always gets mixed up on pet RXs and keep declining my cat's RXs. The vet staff suggested using Chewy and can't believe I didn't think of doing

My local pharamcy always gets mixed up on pet RXs and keep declining my cat's RXs. The vet staff suggested using Chewy and can't believe I didn't think of doing this sooner for this RX. The liquid works and is the same or similar to what I would get locally.
