Wow, I really feel for the guy and, the cats...
I used to be a racehorse groomer. I spent 7 days a week 8-12 hours a day with the same 3 horses. You can't deny the bond and the personal relationship you develop when you work with animals. Every time I had a horse sold on me or, moved to a new stable it was hard on me emotionally. I hope this guy gets those cats back!
