Hoping the medication does work because the taste is not great.

This comes in an oil base and it's in a big bottle. The taste must be absolutely horrendously awful based upon my cats reaction to it, and there is absolutely nothing

This comes in an oil base and it's in a big bottle. The taste must be absolutely horrendously awful based upon my cats reaction to it, and there is absolutely nothing that I can put it into to hide it. I am just hoping that it does what it's supposed to do and I am thankful it's a very small amount. What would be nice would be to have a closed top that you would be able to get it out of instead of having to stick the syringe into it..

Price is unbeatable!

I was having trouble getting the prescription from another online pharmacy so my vet found a pharmacy in town to get it filled, in the meantime I went onto Chewy

I was having trouble getting the prescription from another online pharmacy so my vet found a pharmacy in town to get it filled, in the meantime I went onto Chewy and you had it. It was fast and 1/2 the price of the other two pharmacies. Half the price and fast delivery, win-win for my kitty!

Nice bottle but no syringe to measure dose

Nice bottle but no syringe to measure dose I am not very good at eyeballing 0.6 mL doses.

The medication does what it is prescribed for

We think it works for his medical issue he doesn't like it because of the taste
