Question
how can we stop them from making horrible meows when they are in heat..?

Answer
Hi there!  The only way to stop symptoms of a heat cycle in your cat would be to get her spayed.  Spaying not only eliminates the birth of unwanted kittens that are euthanized every day due to overpopulation in county pounds, but it also eliminates a severe and often times deadly uteran infection called a pyometra.  Spaying also decreases mammary cancers by 98%.
