Phoenix worms/calci worms (same thing) are Ca:P 1.5:1, mealworms are 1:7, according to the table on the first link I posted at the top (scroll down to the table).
Re: Wilko ‘Wildly Tasty’ Insect Medley, do the beetles look like this – http://naturesgrub.co.uk/dried-beetles-from-856-p.asp ??
I only suggest that as mealworm beetles seem to be the cheapest to produce. If so, the Ca:P ratio is 1:11, which wouldn’t be good at all.
I’ll give Purina One kitten biscuits a go… although I live in the middle of a plague of cats :\. I’ll try anything!
