Anyway, it started to look very big, so I got a clinic spot this morning and I set the trap. I took a second trap with me to get another cat that I suspect is female on Second and Central, just in case I couldn't get this one. I set it, went on my way, did my spot on the first half, went back to check it before crossing over Goodman to do the remaining locations, and still, nothing.
So, Spooky will go in to the clinic where he will be neutered, and no baby making for him! Hooray! The other, I will keep trying. :(
Have a great day!
