I go out in the dusk to bring the cat in for his supper. Once I would have circled the house looking for him; now I find it's more effective to walk to the middle of the field, stand still- and wait for him to come to me. I assume it's easier for him to read my energy signature if I'm not moving. He seems to know my eyesight isn't as good as his- so he signals his approach vocally- and I hear him going miaow, miaow, miaow long before I see him. He brushes up against my leg, stands on my foot and then we go back into the house together.
