I've also occasionally looked for evidence that slug pellets are proven to be harmful to hedgehogs, frogs or birds and can't find any.
I do avoid using slug pellets except where they're enclosed (e.g. greenhouse) nowadays though but nevertheless I have no frogs or hedgehogs in my garden. In years gone by in my previous gardens I used lots of slug pellets and had no shortage of frogs and hedgehogs. I suspect other factors are responsible for the decline.
