#sadly the microscopic dogs are cancerous

[thewitchesworkshop]

I hate to bring this up- but scientifically fungi are closer to relation to animals than they are land plants

They are also heterotrophic unlike most plants (I say most for a reason).

So unfortunately; mushrooms are in fact possibly meat. Whatever they are they certainly aren’t plants tho

Here's What You Need To Know About Breast Cancer In Pets

Breast cancer isn't exclusive to humans. This blight affects most mammal species, including your pet dog or cat. A lesser-known fact is that both genders can get breast cancer, although it's considerably rarer in males. Sadly, women and female pets face a high risk of developing the disease.  Although cancer can strike at any time, most cases are diagnosed when the pet is between ten and eleven years old. The breed also seems to play a role. Statistically, Asian cat breeds like Persian and Siamese, among others, are more prone to the problem. In dogs, doctors find it more often in Golden Retrievers, Dachshunds, Poodles, Rottweilers, Spaniels, German Shepherds, and Boxers. But what triggers breast cancer in pets? Once again, all the factors involved are yet to be identified. However, exposure to estrogen and progesterone seems to be a big problem. Especially with pets that experienced copious amounts of the hormones while young. In other words, dogs and cats that remain unsterilized during the first few years also have a higher chance of getting breast cancer. This is due to the fact that estrogen and progesterone play a vital role in their heat cycle. The benefits of sterilization cannot be overstated. Not only does it prevent unwanted litters but it also greatly reduces your furry friend's chances of getting this type of cancer. A spayed animal is no longer exposed to these hormones. Indeed, dogs that are sterilized before their first heat have a microscopic 0.5 percent chance of getting breast cancer. That's a fantastic reduction. Once an owner passes that deadline and spays her after the first heat but before the second, her lifetime chance rises to eight percent. After the second heat, it's 26 percent. As long as a dog remains fertile, she'll be seven times more likely to get breast cancer, as opposed to a spayed animal. Researchers have also identified another risk factor. Pets that are overweight, especially those classified as obese, also fall into the high-risk category. For this reason, the correct diet and exercise are both important to help a beloved pet live a long and healthy life.  One of the most obvious ways that breast cancer is detected is when a vet or owner feels a lump on the underside of a pet's belly. Especially when the lump is near a nipple or in the teat's surrounding tissue. Your vet will confirm their physical examination with blood tests or x-rays. If the results are positive for the disease, more tests must be done to determine whether the  cancer has spread beyond the breast. When there's no sign of spreading, the most common and effective treatment is to remove the tumors. In the laboratory, the tumors can also reveal more about the cancer's specifics and whether further treatment is necessary.  The good news is that breast cancer in pets is hugely preventable. A single operation before the dog or cat's first heat can provide a lifetime cover against a tragic outcome. Read the full article

Body Parts - The Feline Spleen

Body Parts – The Spleen

Ask most people what their cat’s heart does, and they’ll tell you it pumps blood.  How about the lungs?  They breathe in oxygen and exhale carbon dioxide.  The kidneys? They filter toxins from the blood stream and put them in the urine.  The spleen?  That’s easy.  It… it… 

Admit it: you have no idea what the heck your cat’s spleen does.   Don’t be embarrassed.  You’re in good company.  The average person is clueless about all things splenic.   I think it’s time we shed a little light on this most puzzling of organs.

Here are the basics:  The spleen is a dark red organ that looks like a giant tongue.  It is longer than it is wide, and is covered by a thick fibrous capsule.  It is located near the stomach, on the left side of the body, however, the exact location of the spleen isn’t fixed.  Depending on its size and shape and the size of the surrounding organs, the spleen can migrate around the abdomen and visit the right side of the body.

The spleen performs a surprisingly large number of functions.  For the sake of clarity, I’ve narrowed down what I think are the four most important splenic duties:

·      Production of red blood cells.   Most people probably know that the bone marrow is the primary site of red blood cell production.  Well, the spleen is the next major site.

·      Storage of red blood cells.  The spleen holds a fair amount of blood.  If the body was suddenly in need of extra red blood cells in the circulation, the spleen has the ability to contract, releasing red blood cells into the bloodstream.

·      Filtration.  Think of the spleen as a giant filter that traps and removes old or abnormal blood cells from the circulation

·      Immunity. The spleen traps bacteria, foreign proteins, and other microbes and presents them to cells in the immune system, so that an immune response can be initiated. 

You’d think that with all of these important roles, the spleen would be essential for life.  Surprisingly, it’s not.  It can be surgically removed if necessary, and most animals will be fine.  However, it’s certainly better to have one than to not have one.

Disorders of the spleen are much more common in dogs than in cats.  Splenic disorders can be generally categorized as either primary or secondary.  A primary splenic disorder is one in which the spleen itself is the site of the illness.  The spleen can also be affected secondarily by a systemic disease that is occurring somewhere else in the body.

How do we know when something is amiss with the spleen?  When things go awry, spleen-wise, the spleen usually grows bigger.  Enlargement of the spleen is called splenomegaly.  This is not something a cat owner would be able to detect.  Splenomegaly is usually found during the physical examination, during the part of the exam where the veterinarian carefully presses on the abdomen to feel the internal organs.

Splenomegaly occurs in two forms: localized and generalized.  Localized splenomegaly is where one focal area of the spleen is enlarged.  We call the enlarged part a “splenic mass”.  Generalized splenomegaly is a diffuse enlargement of the entire spleen.  Localized splenomegaly is more common in dogs.  Generalized splenomegaly is more common in cats.

Once splenomegaly is discovered on examination, your veterinarian will recommend some diagnostic tests to help determine the cause.  Blood tests and x-rays may provide important information.  Abdominal ultrasound, however, is an excellent, non-invasive procedure to distinguish localized vs. generalized splenomegaly, and to further define the condition.  In most cases, however, a definitive diagnosis can only be achieved by obtaining a sample of cells from the spleen for analysis.  The sample is usually acquired via fine needle aspiration, a procedure in which a needle, attached to a syringe, is gently inserted into the spleen. Material is then aspirated into the hub of the needle and the contents sprayed onto a microscope slide.  The slide is evaluated by a clinical pathologist.  If this does not yield a diagnosis, abdominal exploratory surgery may be warranted. 

Sadly, infiltration of the spleen with cancer cells is the most common cause of splenomegaly in cats.  The most common cancer affecting the feline spleen is mast cell tumor.  Hemangiosarcoma (a very bad tumor; my cat Crispy died of this tumor) is the next most common, followed by lymphosarcoma. 

Fortunately, disorders of the spleen are much less common in cats, compared to dogs.   When they do occur, the prognosis will vary, depending on the cause.
