Taurine is a critical nutrient for cats, who are unable to internally create this amino acid from other amino acids in their diet. This has been long known by the pet food industry, and taurine is added to most (reputable) dry and canned cat foods. So if you are wondering whether this supplement would be helpful for your cat, there are a few reasons this might be helpful:
* you provide your cat with home-prepared food that is a significant portion of their nutritional intake
* you are providing your cat with food that is not intended for cats (eg, dog food)
* your cat is older and might be needing more taurine, since some older cats may have trouble utilizing the existing taurine already in their food
* you are observing symptoms consistent with a taurine deficiency (eg, reduced vision acuity, reduced energy levels, heart problems, etc)
We have an older cat, and have been giving her this supplement for over a week now. She's not crazy about it, but we've found an effective way of administering it is by putting a dropperful on top of her canned cat food that we provide her first thing in the morning. There is no way I'd try to feed it to her directly - I'd lose a hand if I tried to force it into her mouth LOL. (BTW, A dropperful is about the size of a quarter, see photo.) The extra flavoring in this supplement does make it something my cat will eat and doesn't outright reject.
We haven't seen any significant changes in the cat's behavior with these supplements, but think she might be a bit calmer. And thankfully, no symptoms of anything of concern either.
You can decide if this would be helpful for your cat's health - read up on the internet or ask your vet if you're not sure. These supplements, though, appear to be a good way to add this critical nutrient.
