thank you, are there any online places that sell it? Or is the cheapest place at a vitamin shop? Someone I have been chatting with buy's it for their kitty at pet food direct for 61.00$.
I also bought the NOW brand.. very cheap, and no other ingredients.
If you buy other brands, just make sure the 'other' ingredients don't include propylene glycol. Humans can have it, but could lead to blood poisoning (I think that's it?) in cats.
