I'm not trying to sound mean or ignorant, but, too much kitty dander and hair for what? I may be wrong about this, and, I'm not saying your baby should be covered in cat hair or laying face down in it, either. But, I've heard that having them around pets and pet hair and dander can actually help them by getting them accustomed (maybe immune) to certain breathing problems and/or allergies as an older child and adult. Again, I could be wrong, but, that's what I'd heard. Is the cat agressive with the baby? I don't see anything wrong with keeping the cat out of the nursery, and, just supervising the cat and baby when baby's not in the nursery. As far as not having time for the cat anymore, that's really just something you should make the time for. Again, I'm not trying to sound hateful, but, that's just my feelings on it. Is there no one in the home that spends time with the cat anymore? It just seems like if the cat was a part of the family, time would be put aside (maybe while baby is sleeping) just for kitty.
