The most useful thing a lickable treat does has very little to do with flavour. It buys you half a minute of a cat's undivided attention without having to hold the cat, and anybody who has tried to look inside a set of ears, get drops into an eye, or convince a suspicious cat that a visitor is acceptable knows exactly what that is worth.

It is called Salmon, and salmon is the smaller of the two fish in it. Tuna is declared at 22% and salmon at 4%. Neither figure is concealed - both are printed in the composition - but the name on the sachet points at the one there is less of, and that is worth knowing if you were choosing it for salmon specifically. Two other things: Cookhouse's own copy talks about vitamins C and D while the declared additives are vitamins C and E, with no vitamin D figure appearing anywhere, and no sachet count is published for the pack, so there is no way to work out how long one lasts.

Who it's for: owners of adult cats who want a lickable treat that actually declares what is in it, and particularly anyone who needs half a minute of a suspicious cat's cooperation on a regular basis.
