"Four Years Ago My Beloved Cat Moose Went Missing. Yesterday, A Kind Family Who Had Been Feeding Him Recently Finally Took Him To Check For A Microchip"
"The family who contacted had only been feeding him for a week or two. Not sure what his four years prior to that looked like but he was found pretty far from where he was lost so I assume that he moved with a family at some point and then either escaped or was left or what have you. Also he's much fatter than when I knew him so I have to believe he was a house cat "
I guess you've a cat then
