I’m catching them here on tins of tuna!!!i used to use half rabbits and other meat but it’s a pain in the a**e getting it out the cage to refresh it after it’s past it’s best so I decided to try tuna tins and I just cut the lid 3/4 of the way round and pop it up around 1cm(anymore than 1cm and the mice will be away with it)I find it works well and lasts around 2 weeks before I need to change tins which it’s easy and clean to do
