Munchkin is Really Mad Now

I picked Munchkin up from our friend at 4pm. During the trip home he was sitting close to the door of the PTU, getting closer to me, or so I thought. We got home at about 5 pm, and I took him to the water bowl and put a little water on his nose so that he would drink. I had to go get the young beans from my Mothers home, and we got back to the house around 6:30. Munchkin was hiding under my bed and would not come out. I got the Temptations and called the cats into the livingroom, Munchkin came and ate a couple of treats. I picked him up to love him like I usually do and he growled at me. I put him on the computer desk to give him more treats, and I got a quick look at his backside. He is shaved, and I am certain quite sore. He would not eat any more treats for me and jumped down. He is laying close to me, but far enough away to let me know that he is not happy wif me at all. I just spoke to him and he got up and moved away. He also got all of his shots, so he really is mad. I feel so sorry for him.
