Frequently Asked Questions

Will my cat actually eat it? She refuses everything. +

Yes, and this is the part we're surest about. PureSource has no taste and no smell, and it doesn't change her food at all. Just stir one scoop in. Most cats never notice, even the picky ones that reject everything else

How long until I see something? +

Most owners notice a change between weeks four and eight, usually in the coat or energy first. Some cats take a little longer. That's why you get 60 days to decide.

How is this different from the cheaper taurine on Amazon? +

Two things. Cheaper powders are often mostly filler like maltodextrin, so you get less real taurine than you think. Ours is one ingredient, nothing else, and it's real taurine from nature instead of the kind made from petrochemicals. Same idea, very different jar

Does taurine really matter for cats? +

More than for almost any other pet. Cats can't make their own, so they have to get it from food every day. It supports a healthy heart, healthy eyes, and normal digestion. When a cat runs low, those are the parts that slowly feel it.

How much do I give, and can I give too much? +

One scoop a day in her food, scoop included. Taurine dissolves in water, so any extra just passes through her. More isn't better, so one scoop is all she needs.

Do I need to change her food? +

No, and that's the point. It works with whatever she eats now, wet, dry, broth, or raw. Nothing to switch, nothing to fight over. Just stir it in.

My cat seems healthy. Does she need this? +

That's exactly when it matters most. Low taurine gives no warning, your cat looks fine while it quietly builds up over months, and by the time you'd notice, the damage is often done. PureSource keeps her protected before there's ever a problem to see.
