Kathryn was at home one day, petting the formerly female cat boy, Sally, on her lap when she noticed that her cat boys seemed to act strangely today. Many of them were very touchy with each other, even more so than what cats normally were like, with even Sally rubbing on her a lot more affectionately every time she scratched behind his ears or rub his silky smooth back, even going so far as burying his face into her clothes. Even the mailman, who now had full cat ears but still only small whiskers and a small tail squirming inside his pants, seemed a bit more sensitive, his face appearing a bit flushed as he handed the young witch her mail and his legs tense as they rubbed against each other as he walked away, turning just long enough for Kathryn to notice the tent growing in the crotch of his pants as he walked away.
Her suspicions were soon confirmed as she turned back inside when she heard a strange meow coming from the living room. Walking briskly in stride, Kathryn walked through the adjoining door just in time to see Tim popping his cute little cock into Kevin's smooth rump. She sighed with a smile, shaking her head as she realized that it was mating season for cats and being cat boys was no exception to this fact as her two favorite kitties began going to town in the middle of the room, Kevin sensually rubbing his cheek into the soft carpet while Tim began humping him furiously, both of them meowing lustfully.
Had she not been a witch of her caliber, she would have been furious at the mess they were about to make, but magic was such a convenient thing, and with her mastery over it, Kathryn was easily able to cast a cleaning spell onto the entire house, inside and out. So despite pre that Kevin's cock was now shooting all over the ground, all of it would disappear into nothing before any stain could make contact with the surface.
And speaking of which, another meow in the study she was lounging in earlier confirmed that Sally had now found himself a mate among his former classmates, specifically one of the other few girls present in class at the time. "Aw, you two must have been best friends~!" Kathryn said as she pets Sally's back as he humps his partner. "Well, you still get to stick together and now both of you are getting to know each other even better!"
Sally and his partner could only meow back before immediately going back at it, with Sally quickly unloading his cum into his partner, causing him to spurt all over the floor as well. The young witch simply chuckled at their behavior. "I guess we can confirm that there's only one thing that cats in heat have on their minds!"
