I don't know what to do! Dory was spayed on Monday, and when I came home from dropping her off at the vet Vader, our other cat, was very cuddly and more affectionate than usual. It was like he was glad she was gone. I brought Dory home on Tuesday morning, and now Vader is hissing at her and me, and starting to actually bat at her and try to attack her when she gets too close to him. Before this they got along great and cuddled all the time (after an initial adjustment period when we got Dory last July). This is making me so sad! I have Vader locked in the basement (with food, water, litter, etc.) and I have Dory upstairs with me. I don't want Vader to feel rejected, but I don't want him hurting Dory and popping her incision open. I'm also afraid he'll hurt her feelings, honestly. He's kinda pissing me off! What do I do?
