He really should have thought it through better, but I would assume your husband was trying to do something sweet. Perhaps because whatever he took as your reasons for not getting a dog wouldn’t apply to a kitten, he thought he’d found a good compromise; I don’t know. In any case, I’d suggest forgiving him and giving it a chance, but also gently letting him know that you felt left out and disrespected because he didn’t ask for your (name removed by moderator)ut–and that in future, you’d appreciate him asking you how you feel about it before making a final decision on similar things.
Overall, though, I agree with Corki. As long as hubby is willing to keep the litter box clean (and you should probably talk about how often this should be done to be sure you’re on the same page here–if there’s disagreement, maybe check with your local veterinarian for recommended guidelines), I’d give it a little time and see how it goes. Of course, if he’s
not willing to completely take care of litter box duty, then yes, kitty should go back or hubby needs to find it a new home.
Cats, even kittens, are pretty independent and generally don’t require a lot of attention other than food, water, litter box, and occasional snuggles (though it does vary by kitty). They can be very entertaining, too. The cats we’ve had usually liked to cuddle or simply sit nearby when I was feeding the baby or reading to a toddler (though our current cat prefers to stay outdoors, and mostly ignores the kids and the dog, lol). And if anyone happens to be allergic, you’ll discover it early enough and can deal with it then.
My kids have been raised with both dogs and cats (as well as a few other pets), and I’ve found that cats are usually much easier to deal with than dogs when you have little ones–but I do suggest making sure the cat has a place it can hide and/or climb up to when it wants to get a break from little grabby hands once the baby becomes mobile.
Best of luck!
P.S. The risk is pretty small, so hubby keeping the litter box clean should be enough, but if you’re concerned about toxoplasmosis, you might ask the vet about testing your cat for it.
