When you share a home with a feline friend, you hear many cat sounds throughout the day. And although you can easily figure out the meaning of some cat noises (circling their food dish and meowing while looking up at you, for example), it's not always that obvious. What do cat meows mean? You may simply be the pet parent of a chatty kitty. This is especially common with older furry friends, as cats become more vocal as their hearing worsens.

Here are some distinctive cat sounds and what your cat might be expressing through them.

1. Meow

Why does my cat meow so much? As a pet parent, you've likely asked yourself this many times, and you've already concluded that your cat emits a classic meow for a variety of reasons. But cats rarely meow at each other, so what is your cat trying to tell you? Cats speak to you with different meows depending on the situation:

Their Breed Is More Vocal

Some cat breeds meow more than others. Siamese, for example, famously "talk" a great deal with distinctive raspy meows. The ASPCA points out that "some breeds of cats, notably the Siamese, are prone to excessive meowing and yowling," so you may just have a loud little pal. The quiet Chartreux breed, on the other hand, rarely meows. Knowing your cat's normal helps you recognize if increased or decreased vocalizations signal problems.

They Want Something

Beyond breed, what do cat meows mean? Meows can express delight, especially when mixed with other vocalizations like trills. A typical cat meow demands something. It starts out polite, short and sweet in a moderate tone. Common meow demands include: fill my bowl, open the door, clean my litter, play with me and pet me now. Meows may become longer and more drawn out as your cat waits to be addressed. Pitch lowers as cats get more insistent and grows more strident when they feel ignored.

They're in Heat

Intact female cats meow loudly with a unique tone during estrus. These cat calls and yowls announce her receptive state and alert male cats that she's ready for romance. Spaying eliminates estrus-related cat sounds.

They're Stressed

Stressed cats meow repeatedly. Any change to your usual routine — a different work schedule, moving or adding new pets to the home — could cause your cat to meow more than usual. Health issues can also increase meowing. Cats might cry in the litter box from painful elimination. Old cats who are losing their hearing may cry loudly when they can't hear you. Increased meowing can also signal hypertension, or high blood pressure, so see your veterinarian to screen for potential health conditions.

2. Purr

Life doesn't get much better than when your cat snuggles up to you, nuzzling and purring at the end of a long day. As Trupanion notes, kittens are born blind and deaf, and they first communicate with their mom through purrs. All cats use this method throughout their lives — even with you. Pay close attention to your cat's purrs and you'll notice subtle changes in tone and vibration.

Purrs express emotion. In most cases, they mean your cat is happy and doing just fine. Cats also use purrs to calm themselves when they feel stressed, scared or in pain. Cats may even purr in their final moments. On a happier note, the frequency of vibration in cat purrs can promote bone healing. Think of purrs as a kind of feline vibrational medicine that makes cats and their humans feel better. Give your fur baby lots of love when you hear their little motor running.
