Unbeliefably, Jake returned tonight. I opened the deck door when Skeeter returned and Jake ran inside. He attacked Skeeter and I had to chase them around a while to grab him. I was VERY angry. When I finally grabbed Jake, I tossed him into the basement rather uncerimoniously. To Skeeter's credit, he was fighting back real hard.
I went down to the address where Jake was supposed to live, and no one was there. Then an hour later there was some incoherent jerk there who said he was a relative. Finally, an hour later, I found Jake's actual people. They were real nice. I got them to come back to the house and brought Jake out to them. I mentioned that that a lot of places do neutering and microchipping real cheap, and they say they will do that.
They say they will have Jake neutered soon. If they don't and he returns again, I will.
