Wouldn't it also depend on why the trapping is happening....I trapped cats in our yard, we trapped 3 UN-NEUTERED feral cats with FIV, two with FELV and a few others. Two of my own cats now are ones I trapped. Bob was wandering outside for at least a full year when I finally trapped him. He has massive scars all over his body from probable fights he had been in with God knows what, and he had a nasty case of fleas. And he is declawed in front!
May be my opinion, but whoever had him didn't deserve to keep him, being in that condition when I got him. Timmy, I trapped when he was 5 months old, and extremely feral. It has taken him nearly a year to warm up to me, and I'm the only one he lets near him, and still only when HE allows it. My intentions were always for the good of the cats. I didn't know much about TNR before so we were just trapping cats and giving the non-diseased ones to our cat association, who are a no kill shelter, and they would first run an ad for 2 weeks about the missing cats, before treating them for whatever they needed, altering them and then adopting them out. We don't trap anymore, but for the record, our traps were always cleaned with bleach and water after each cat, and a full can of food and bowl of water was always placed inside, so they never went hungry or thirsty. The trap itself was incased in a rubbermaid container with just the end sticking out, and blankets inside too, to protect the cats from the elements, and the trap was on the porch. The trap was checked multiple times throughout the day, late at night and first thing in the morning. So they, if a little scared, were well cared for even while trapped.
I would talk to the man and see why he trapped the cat. He may be working with a rescue.
