My cat welcoming me home

My cat’s “welcome home“ show after I returned from a 3 weeks holiday. (He was not hungry or sick, since I arranged for someone to check in on him every couple of days. I guess he was just happy to see me.) EDIT: Reading the comments I find it necessary to do a little recap, hoping to make things clearer: * The cat had everything he needed (food, water, litter, toys).
