I agree I'm allergic to them and we won't know if Kadence will be or not we have had them since before Christmas her dad told her we could keep them for a few weeks turned into months and they were doing fine till I found out they weren't using their litter boxes

You should tell her if she doesn't get them out then they're gone simple as that you can't risk your babies safety and health over someone else's pets they're her cats not yours she needs to take care of them
