Trapping day

Clinic day tomorrow, so today I went out with traps and allgedly irresistable bait in the form of warm KFC. And first crack out of the box, I got the Black! Big honkin' black tom; same size as Big John and probably a constant rival and combatant. I really wanted him, because I'm told he has a bad habit of spraying on A/C units, which carries the smell into the buildings! NOT the way to keep our little colony unobtrusive and unnoticed. So I'm glad to get him; now I can really stave off those silly employees who say he's "mean" (I keep insisting, "he's not 'mean', he's a dadgum feral and a TOM to boot; he's doing what feral toms do!" but most people don't get it.) Next one I caught was Billy Jack, who promptly got renamed Billie Jean when I got a good look at the undercarriage. Dammit, it looks like she's had a litter fairly recently, which may explain her excessive food aggression; she stands over the food dish and screams at anyone who approaches. Most of the rest of 'em can share a dish pretty peaceably, but since BJ showed up, I generally have to give the others a little palmful apiece to tide 'em over while she's bogarting the communal dish. With any luck a spay will take care of that too.
After that it got complicated; Yellow Fellow and Little Joe kept sneaking into the traps and eating the bait trail, even after I shooed 'em off several times. What do I need to do, bring extra traps and trap up those idiots just to keep 'em out of the way?? Arrrggg...
