If you look at the added things in the liquid, in the link you posted, you will see it has aloe Vera juice ( which as far as I know is toxic for cats....Aloe Vera plants certainly are very toxic) and potassium sorbate, potassium benzoate, vegetable glycine and natural flavouring. I am not sure of the rest of these additives, if they are safe for cats but personally I would stick with one that is tried and trusted.
