The Great Outdoors!

Billy has discovered what lies beyond the front door....UNFORTUNATELY!!
He is now obsessed. For about the past month and a half, Billy and Joey have been waiting at the front door, any time we go outside. If we leave for awhile, they are usually not there when we get back but if we re doing yardwork or anything, they will wait right inside. Joey likes to walk to the door, and Billy has always walked to the edge, but never outside. This is part of why we think Billy can see some shadows etc, bc he likes the outdoor light a lot.
Anyway, last week Korey decided to take Billy outside and see what he did. We let him down on the grass in the yard and he just walked around a little and ate some grass and laid in it. We didn't let him out very long. Then, a couple days later we were sitting on the steps and brought him out again. He laid on the concrete and rolled around and cooed/purred happily. Now, everytime we open the door, he rushes over to try and get out the door. He doesn't want to go far, just onto the porch and then he lays down. We joke that he has the spirit of our kitty Deke who passed a few months ago, and LOVED being outside with us. No other cat is allowed out, because they try to explore beyond the porch and we are afraid they will run away.
Billy has also started spraying :( We think that is what it is at least...so in the morning I am calling to get an appointment for him to be neutered. I am VERY worried about leaving him at the vet. Joey, who can see just fine, was so lovey and clingy once he got back from the vet after his neuter...I worry with Billy it might be worse. Billy took to us very well when he first came to live with us, and is very friendly to new people, so I am not worried about him being scared of new people....more worried about him going to a scary new place, without his human mommy and daddy, and having to go through the neuter and wake up disoriented without our comfort.

Billy is still the most amazing cat. I love love love Joey, and he is my little baby, but Billy is fantastic. Billy loves Korey so much...he will climb on me and realize I am not Korey, and go find him :). Billy also likes to climb onto Korey's chest, and "nurse" from his chin!! It is so funny! Billy will paw at his face, and lick his beard and just nestle into it. He is so attached to Korey.
We are going on a mini vacay in a couple weeks, and it will be Billy, Joey and Toby's first time without us overnight...we will be gone for three days! We have someone watching the house, but Joey and Toby hate new people and Billy just loves everyone, so we are hoping they all still love us when we get back.
