Congrats!! He is just gorgeous!!

Now, lemme tell you. I don't think you'll have much trouble. Over a year ago we got our siamese girl Lily as a sister for our tabby boy, Toby. Toby was an adult and lily a kitten. They are two totally different cats! They have NOTHING in common. Lily is social and hyper. Toby is shy and lazy. But if THEY can learn to tolerate each other, I'm sure yours will be fine!

We introduced them as soon as we got them and kept them around each other while we were around, and put Lily in the bedroom at night. Lily hissed a lot at Toby and occasionally swung at him, and this continued for weeks. But after they realized no one was going anywhere, they just did their own thing and tolerated each other. They eventually started having fun rompsing and fighting together, and OCCASIONALLY (keyword) cuddled. They are the same today.

I wouldn't worry about Miska hating you .. cats are very forgiving! Just make sure you give them both attention. If you pet one, go pet the other. I notice that if I'm petting say Lily, Toby will look at me and almost say "Umm .. hello? I'm here .. " So I have to go and rub his belly too ..

Good luck .. if you have any questions just ask
