@aroundthehills great material for building mattresses in nests!
On my balcony I usually put some material for… the ‘flannel’ sheets. I divided the clumps of cat hair into smaller tufts that are easy to carry, and put them into a clean suet feeder.
Blue tits and great tits do appreciate: one refill per week since the beginning of March!
