Quoting LilyRain12:" and for the record, even if it was new clean carpet i wouldn't leave her on the floor for long anyway. ... [snip!] ... floor for long anyway. she puts her hands in her mouth a lot and any carpet/floor will be dirty no matter how much you clean."
I don't know what kind of household you're running but my floors aren't so dirty that my son can't be on them. In fact, I don't know any parent who feels they can't let their children crawl around on the floor. It doesn't take much to sweep up a mess or mop a floor. Seriously.
Rip that nasty ass carpet out, pay someone a cheap amount of money to put new carpeting in, and confine those nasty cats to a room where they can't piss on the rug your daughter should have access to so she can learn how to walk one day.
Another thing, ammonia from all that urine is wreaking absolute havoc on your health as well as your daughter's whether you realize it or not. That stuff is TERRIBLE for people and animals alike. Not only are the people in the house suffering but so are the animals.
I understand money doesn't fall from trees but there is no excuse to raise a child in a home with a piss-soaked carpet. I don't care if the cats have a disease and would end up dying (what do they have, anyway? Feline leukemia? In that case they should be put down...) because pets should come after your children. I can't believe this is even an issue. I don't mean to sound like an ass, OP, but you're making a lot of excuses right now and that's why everyone is getting so upset. The thought of a poor, defenseless eight month old not being able to grow into a happy toddler because of ammonia-soaked floors is absolutely infuriating. I wish I could be nice about this but you still don't seem to understand so now people are having to get more stern.
