Ugh on the squirrels gobbling up all that nice birdseed mix, Sally! So far they are staying away from my spicy PB and bird cookies (PB suet, also extra hot). But the last couople of years we had one who obviously couldn't taste capsicum, just munched his way through it with no reaction other than, "yummy!" Apparently you have one or more like that. I wonder if it will become a more predominant trait?
