I recently came across an extract I had copied from From Wildlife on line – European hedgehog.
‘Hedgehogs have a propensity for eating almost anything and will readily consume high fat foods (e.g. cat food, processed meats, etc.) put out in gardens and if offered in captivity. Hedgehog metabolism is geared to the digestion of high protein invertebrate prey and unrestricted access to high-fat foods can result in fatty liver disease, obesity and coronary complications as is seen among humans.’
Which seems to confirm the feeling I had that suet pellets are not a good idea for hogs.
