We have been manufactoring these high protein foods for a few years now, using seed of many types ground up into a fine powder before being packed into resealable bags before being sent out.
As for feeding these foods, they can be fed either dry on top of their other foods or fed seperate just mix with a little water till its between a soup and porridge consitancy, you may need to experiment to see what you snails prefer and only feed 1 - 2 times a week.
Nothing else is added to the foods other than the seed mix and flavourings. NO calcium is added to the foods as this can be harmfull to the snails, forcing them to eat calcium with their food, Yes they do need calcium in their diet this is best to give them this seperatly ie. cuttlefish bone,
All the flavourings we use in the making of these foods are made from the freshest stock we can find, We have approx .30 different flavoured foods in 3 different size packs.
A bit about us
We are a small family run business I( 2 of us ) n the West Midlands, During the first covid shutdown I started keeping snails and many isopods and after losing my job started supplying isopod supplies to the public mainly high protein snail foods at first now we have added quite a few items.
Keeping these snails and isopods myself I can try out my ideas on my own pets before releasing them for sale to the public.
