well i was thinking its because hes hungry so i think i will try to get the kitties a different kind of kitty food that they might like better that might get him to stop. i worry so much when i wake up in the morning and see just the intestines of the mouse on my back patio. he only eats the mice he kills nothing else thank god. what would be a good brand of cat food i give them friskies right now and have been for years. seems like its time for a change.
