Thank you for the advice. They did well last night and Koba, my adult cat actually layed with me for an hour like he did before Stinky Pete, the kitten came. The vet said he can’t be neutered until May so that will have to wait. I say a lot that I will send Stinky Pete packing but I honestly would never do that. He is with us til I pass and at that point one of my kids will take them then.

We are already past the introduction and at first they were fine and all was well. The healthier the kitten gets the more aggressive he gets. My adult cat will not return the aggression. I honestly don’t understand it either
