Your pet is being treated by the same expert helping shape how Chagas disease is understood nationwide.

Chagas disease is caused by the parasite Trypanosoma cruzi, transmitted by “kissing bugs” commonly found in Texas.Once infected, dogs may appear normal while the parasite attacks the heart and other organs.Without intervention, Chagas can lead to:<ul><li>Heart disease</li><li>Arrhythmias</li><li>Sudden death</li></ul>

Early Detection. Advanced Treatment. Led by One of the Nation’s Top Experts.

Do not wait for symptoms to appear.

Chagas disease progresses in stages. The earlier it is identified:<ul><li>The more treatment options are available</li><li>The better heart damage can be managed</li><li>The higher the chance of improving quality of life</li></ul>Waiting can mean irreversible cardiac damage.

If your dog may have been exposed to kissing bugs, do not wait. Chagas disease can silently damage the heart before symptoms appear. Early diagnosis can make the difference.

Chagas disease is often silent early on, but warning signs may include:<ul><li>Lethargy or decreased activity</li><li>Fainting or collapse</li><li>Irregular heartbeat</li><li>Difficulty breathing</li><li>Unexplained weight loss</li></ul>If your dog spends time outdoors, lives in Central Texas, or has been exposed to insects, they may be at risk even without symptoms.

If your dog may be at risk, schedule an evaluation today and get answers from one of the leading experts in the field.

Purring is the most common sound a cat makes and what owners are used to. Yet we know less about the unique sound than meowing, hissing, and growling. Many cat owners are taught that cat purrs are to show that the cat is happy, although a cat’s meow has more meanings.While purring is partly instinctive and voluntary for cats, cats can use the purr sound for various reasons, such as using the soft rumble to communicate as a form of healing or self-soothing. This is why cats will purr whenever they are in pain, injured, or are in a stressful situation.Here is what you need to know about cat purring. This article will inform you how they purr, how you can tell what your cat’s purring means, why they do it, and other facts about cats’ purr.<h2 dir="auto" style="text-align: left; line-height: 1.1">When&nbsp;Do&nbsp;Cats&nbsp;Start&nbsp;Purring?</h2>Cats begin to purr after a few days of being born. Kittens are born blind until two weeks old. When they are blind, they use purring to communicate with their mother to alert them on where they are, and to draw their attention when they are getting hungry or when it’s feeding time. Cats carry this behavior till adulthood and will be familiar to cat parents whenever it’s time for dinner. These are just a few of the ways purrs are used by cats.<h2 dir="auto" style="text-align: left; line-height: 1.1">How&nbsp;Do&nbsp;Cats&nbsp;Purr?</h2>When a cat purrs, nerve signals are sent to the muscles of the voice box and diaphragm, which helps expand the chest once breathing. These nerve signals stimulate the vocal cords, so when a cat takes in air and exhales, the air in the diaphragm moves across these muscles, resulting in the purring sound of both domestic and wild cats.Purring has developed throughout the years to help keep cats’ bones and muscles intact at all times. This is extremely useful during long periods of inactivity, like the hunting style, when they have to wait a while before they pounce on prey and ambush it. The cat's purr is almost a continuous sound. A cat’s purr is when they both inhale and exhale.Scientist used to believe that cat purring would usually come from the vibration of their hearts, and if you felt your cat purring, you would know why they used that theory. Air vibrates whenever the cat inhales and exhales at approximately 25 to 150 vibrations per second.<h2 dir="auto" style="text-align: left; line-height: 1.1">Why&nbsp;Do&nbsp;Cats&nbsp;Purr?</h2>Cats purr for different situations, which causes multiple theories on the sound they make. Here are different reasons cats purr.<h3 dir="auto" style="text-align: left; line-height: 1.1">Your&nbsp;Cat&nbsp;Is&nbsp;Happy</h3>&nbsp;Cat’s owners are used to hearing their cat purr whenever their cat is content and happy. It’s like how a dog wiggles its tail and jumps, all excited.Your cat is sitting on your lap and getting pets and scratches. They are probably purring to inform you they love what they are receiving, a nonverbal way to communicate with their owners without using words, but sounds. If your cat is receiving love and it purrs, you don’t need to worry; just keep showing your cat love.Humans laugh and dogs wag their tails when happy, cats produce a low rasping vibration sound that is often heard when they’re being pet or scratched. Cats can purr to other cats or even other pets like dogs.&nbsp;<h3 dir="auto" style="text-align: left; line-height: 1.1">Your&nbsp;Cat&nbsp;Wants&nbsp;Food&nbsp;or&nbsp; Something Else</h3>&nbsp;Sometimes cats purr whenever they are hungry or want something. Researchers have differentiated the purrs of content versus hunger. The purr sounds like their pleasant purr and a whining purr, like a child whining or crying. Cat owners are more likely to respond to the sound.<h3 dir="auto" style="text-align: left; line-height: 1.1">For&nbsp;Healing&nbsp;Mechanism</h3>&nbsp;Although purring takes so much energy, cats use this sound as a form of self-meditation or relief from pain and recovery whenever they are hurt. It’s simply a way for cats to soothe themselves, similar to a child that sucks their thumb to feel better or a man humming or talking to himself.According to studies, purring is done at a low frequency that helps to stimulate the injured area to make it feel better, including most of the tendons and bones. The frequencies of the purrs cause vibrations within their body, which can:<ul><li>Reduce pain and swelling</li><li>Ease breathing</li><li>Repair tissues, tendons and build muscles.</li><li>Heal bones and wounds.</li></ul>This might explain how cats are able to survive falls and the theory of cats having nine lives. They also tend to have less complications after a surgery than other pets.
