Thanks Elizabeth, I have had a look around and it seems that a lot of people are more keen on the Clarks diet which they reckon is better. There is now a distributor in the UK and the prices are pretty much the same as Repashys from stickyfeet. As far as I can see, the Clarks is a single part whereas the Repashys needs to be two parts mixed together, is this correct? Do any of you experienced keepers have a particular preference and why?
