Discussing the Horse’s Appendicular Skeleton.
The appendicular skeleton is comprised of the fore and hind limbs. The fore limbs do not attach to the spine at all, instead they are suspended with muscles and tendons. Which give the horse more agility so that they can do things like folding up their legs when jumping. The hind legs attach to the pelvis and even though they support only 40% of the horse’s weight, they produce the most forward motion and the stabilization attachments to the spine. So the next time you are with a horse, think about this and don’t forget to have fun!
Concerning Horse’s Diet.

Obviously, the most natural thing that a horse can consume is green grass. It is also the most nutritious thing a horse can ingest. Grass contains Silica, which promotes dental, hoof, and bone health. For most people, it is hard to find fresh green grass in the winter. These people can buy their horses hay. Although good hay can be quite nutritious, it still does not have as many health qualities as fresh grass. Some people supplement their horses with grains, oats being the traditional choice. Horses can also eat (good) corn but grass seed heads are the closest thing to what horses eat in the wild. When it comes to grains (or any other food) fresher is better. With all the processing going on nowadays grains can lose much of their nutritional value such as silica. You can also get your horse concentrate mixes. These mixes contain things like flax, beet pulp, molasses, bran, vitamins, and minerals, usually to make up the shortcomings in your horse’s diet such as in the winter when the horse is not getting much grass or to give the horse energy. It is also a good idea to give this mixture to pregnant mares to keep their health up so that their foals will most likely be healthy. You can also give your horse salts and minerals in the form of a salt block so that your horse can satisfy its cravings whenever it wants. Just for a little fun fact, reports have shown that horses will usually crave salt more in the summer than in the winter. So keep your horse happy, healthy, and content with a good diet and plenty of exercise.

Concerning Cat’s Diet
Being Carnivorous, cats eat a variety of birds, mice and other animals. Although they ARE carnivores cats also ingest grass. Usually they do this to rid themselves of something irritating in their stomachs, but sometimes cats just like the flavor of grass. Regarding food, there are two kinds of food which you can buy your cat, canned and dry. Canned food is relatively easy to store and the best kinds are very nutritious but are also exorbitantly priced. While dry food is less expensive it is low in fat and believed to cause bladder disorders in older cats. So if you don’t want an unpleasant surprise, look into your cat’s food and make sure to get good stuff. Your cat deserves it!

The Domestication of Cats
When where cats first domesticated? Apparently most people think it happened in the Middle East. Ancient Egyptians (who also worshipped cats) kept cats to keep the gluttonous mice from devouring their grain stores. Around that time traders brought cats to Italy where they were lovingly accepted. Soon all of Europe wanted cats and they even made their way to America via ships. People who own cats are very lucky, because cats are usually good natured and long living.

Regarding the Horse’s Axial Skeleton
The axial skeleton is the part of the horse’s endoskeleton* that contains the skull, vertebrae column, sternum, and ribs. If you are not familiar with the skull, ribs, ect, this is what they are composed of. The skull has 34 bones and 4 cavities, the cranial cavity, the orbital cavity, the nasal cavity, and the oral cavity. The cranial cavity encloses and protects the brain. While the Orbital cavity surrounds and protects the eye, the oral cavity is a passage to the respiratory system and the digestive system, and finally, the nasal cavity leads to the respiratory system and also includes the extensive pericardial sinus. Moving along, the vertebral column has about 54 bones including 7 cervical (neck) vertebrae, the atlas and axis which support and move the skull, 18-19 thoracic (the vertebrae that the spine is mostly made from) vertebrae, 5-6 lumbar (lower back) vertebrae, and 15-16 caudal (tail) vertebrae. Although, the number can be different according to different breeds of horses. The Arabian for example only has 5 lumbar vertebrae, and 16 cervical vertebrae. The sternum is located on the back of the pelvis and is the part that the backbone attaches to, usually having one or two of the lumbar vertebrae fused to it. And ultimately, the ribs, horses usually have 18 pairs of ribs but the Arabian has 17 pairs. The ribs are used to enclose and protect the vital organs such as the heart and lungs. So the next time you see a horse, think about all the interesting things I have told you today and make sure to check out next week’s blog about the horse’s Appendicular skeleton.

Concerning Cat’s Playtime.

Cats, being carnivores, (which are the most playful mammals) base their play on rehearsing the skills they need to survive as a predator such as hunting, fighting, and killing. When kittens play chase, they play the roles of pursuer and pursued switching frequently and learning the life of a predator. Obviously sometimes a kitten might get a meager scratch or bite but it is rare that they would get injured during play. Playing, cats are never scared or distressed and it is obvious that cats enjoy interacting in this way. If you only have one cat, make sure that your cat is not bored by giving it toys or letting it outside.
Discussing the Equine Heart.

A horse’s heart has a more rounded shape that a human heart and is also smaller compared to the horse’s size than a human’s. The horse heart is composed of four sections, the left and right atria and the left and right ventricles. When a horse reaches maturity its heart usually weighs 7.5 lbs, but it can weigh as much as twice that amount. The horse heart grows until the horse reaches four years of age, but sometimes (usually because of a condition) the horse’s heart might grow a little more. There is a component on the horse’s hoof called a “frog”. Located in the digital cushion, the frog aids the heart by helping to pump the blood up the leg. How this works is when the horse walks, (trots, canters, gallops, ect.) the frog is compressed against the ground and shoots the blood up the leg. That is why a horse can go lame if it stands around all day and doesn’t get enough exercise. The heart is not strong enough to pump all the blood up the horse’s long legs, and consequently the horse will go lame. Usually in the back legs first as horses tend to move their front legs more. So make sure your horse gets enough exercise and ride often to get that frog pumping to ensure your horse’s health.
