kitten in the litter boxCat feces may contain a parasite that can cause a serious infection. This infection can lead to birth defects. The chance of becoming infected is small, but it is best to be cautious. You should not change the kitty litter if at all possible. If you have to change the litter, use rubber gloves, wear a mask and wash your hands afterward. You should also wear gloves when gardening as neighborhood cats may have used the area as a litter box.
