Thanks for all the responses. I'll clarify a bit on the pet choice. He wants a cat because I said no dogs right now and he is just an animal lover. I worry about rescuing any age dog besides a puppy with kids in the house and training a puppy is a lot of work that i alone would be taking on ( kid's at school hubby at work). I grew up with dogs and cats and cats as far as house training were much easier especially when we were older and on the go. I feel that the kittens (we'll get two if we do adopt them) will give him the companionship he is craving and it won't be as difficult. I am home all day, but evenings and weekends we can be gone for activities a lot and I think that is much harder on a dog than the cats IME. Plus while most cats are active and enjoy toys and play time we've always had to walk our dogs and run them in the yard multiple times a day to prevent naughtiness and restlessness and again find cats to be not quite as needy in this way.
I looked into "hypoallergenic" breeds and we'd have to go through a breeder to gurantee the pedigree and to get two would run us between 1500-4000 just to get them, not including vet care and supplies. That is a lot of money.
I don't want dh to be miserable but he is fairly confident he'll be fine, but that is him. He doesn't complain and is go with the flow. It is me who worries about everyone. The advice many have given is what he says we'll do to keep it under control. I am a cleaning freak so that is no issue.
Maybe I'm being selfish for not getting a puppy and do admit to feeling guilt that dh would tough out stuffy noses and watery eyes because I don't want to add the responsibility of all the training that comes with a puppy.
