The feral cat that has been coming to our house over the course of the winter has had her kittens. We walked the tree line & couldn't find anything. Nor could we hear them. We also have a 3 year old burn pile of leaves & tree limbs that they have been sleeping in..all the strays..No kittens in there either. where would she have had them? There are holes all over the brush piles in the far tree line..but there are also much larger animals over there. Coons & the like..I would like to catch them before they are here when they are 3 months old & getting into everything here.
