Awww, Ellen, I feel so much empathy for your son and you and all the pain you're going through. Tell him that although it's true he won't get Henry back, he should look at other cats and give them all a fair chance to "click" with him. Just like people are unique individuals, so are cats. Henry charmed one way, but another cat can be equally charming and lovable in a different way. He should look for a very bright and "upbeat" cat that loves to interact with people. Some cats play fetch. Some will walk on a leash. Some talk a lot. Maybe an Oriental or even a Siamese might be a good fit. The solid color Orientals are a bit more laid back than Siamese. Maybe your son could volunteer to work with the cats at a no-kill shelter for a while. They say shyness is selfishness, and I think in a way, grief is selfishness after a certain point. Grieve a while, but then move on. Truly, I have no regrets that I brought home 2 cats (from a kill shelter) just 2 days after I had to have my precious guy euthanized. I honestly think it was the absolute best thing I could have done, for those cats and for me. It was very traumatic to lose a beloved cat that I'd had for 16 years, but there were those 2 little faces there at the shelter saying "Pick me! Pick Me! So I just picked them, because they picked me first, and off we went and lived happily after.
