Most animals will chew on almost anything that has a scent.
So sometimes that includes the litter people carelessly drop instead of putting it in the bin.
Animals can hurt themselves by swallowing or choking on things they're not meant to be putting in their mouth.
Litter is pollution
Dropping litter on the floor is also very damaging to the environment, and it's a form of pollution.
Please, if there is a bin near put your litter in there.
But if there isn't a bin close by, hold on to your litter until you get somewhere where there is a bin.
Loads of kids drop litter but you don't have to."
