TL;DR at the end. This is a long one.
We just got 2 new kittens (not sure the age but too young to know gender still) and we haven't yet introduced them to our other 2 cats (1 male of about 9 yrs, 1 younger female). The male is named Bandit, for reference. I wash my hands before and after handling the kittens and we keep them in their own small-ish room to stay separated untill they have their clean bills of health and can be properly introduced. However, Bandit caught a glimpse of one of the kittens earlier today. My dad was holding a kitten and petting Bandit at the same time. Bandit had already seen the kitten for certain and was loving the pets, no problem. Then, all of a sudden, with seemingly no trigger, he hissed and ran off. A few minutes later I went to him with treats. He was hiding in a corner of the house, the same corner that he hid in when construction workers came and he was afraid. He hissed at me when I offered the treat so I set it down for him. Still wouldn't eat it. I remembered that I hadn't washed my hands, so I left him with the treat to do so. When I came back he still hissed and refused to eat the treat, cowering farther away from me. I decided he needed his space and left him alone for a while. When I went upstairs a few minutes later for bed he was already in my room, trying to find a way under the bed (there is no way). I picked him up and placed him on my bed. He went to his favorite spot in front of the window and seemed fine. He let me pet him and kiss him without a problem. I opened my door to talk to my mom and when I went back to my room, door still open, Bandit hissed. I couldn't tell what he was hissing at, then I saw our other resident cat (Vixen) sitting across the hall. My mom went to hold Vixen and carry her to Bandit so he would know that she is not one of the kittens. He still hissed, so we set her down and let her walk away. (She has been interested yet 100% unbothered by the new arrivals, but she hasn't met or seen them yet). He is currently sleeping in the corner of my room with the most cover rather than his window spot which he sleeps in every night, except for the nights when he sleeps next to me. He had a similar reaction when we introduced Vixen, but when he hissed at her and even me I got really scared.
TL;DR
I just got 2 very young new kittens. I have 2 resident cats (Older male Bandit and Younger female Vixen). Vixen is aware, interested, and unbothered. Bandit is aware and afraid. He seemed to be aware and unbothered, in the presence of a kitten yet loving the pets he was getting. Suddenly He hissed and ran off and ever since he has been acting off. He will hide and reject treats. He hissed at me and Vixen even when I had washed my hands to get the kitten smell off. He always sleeps on my bed with me, but tonight he sleeps on the floor of my room.
TL;DR For Those Who Really Don't Like to Read
I got 2 kittens. I have 2 cats. Alpha male is hissy at everyone on and off.
CONCLUSION/QUESTION
I'm really worried for Bandit. I think it is a territorial problem. Since we don't yet know the genders of the kittens, I think it could be a huge problem if both are male. I need tips for introduction and to help reassure Bandit. (Out of Eat/Play/Love, his priority is Love or Eat.) I need anything that can help keep him calm and everyone safe and happy.
