I have a family that has 2 1 year old kittens at their home. Unfortunately, it seems almost every morning, the kittens pee on a backpack, or in the laundry, or like today, in a boot. The mother will rinse it out, but because there is no back up boots, the children get sent in the boots. Today, my place stank of cat pee. It was horrible. I have two kittens (the exact same age as theirs), and I, well, hubby, goes out of his way to ensure that the litters are changes CONSTANTLY, to avoid the smell of cat in the house. I sprayed a bunch of air freshener this morning right after she left, in hopes that the net parents arriving, did not smell it and think that it was my house I am not sure if there is anything that I can do Luckily, they are only b/a school kiddies, but my lord, the smell is strong. I am just hoping that it is my pregnancy sniffer that it making it SEEM stronger then it really is.
