External Parasites in Cat

Cats have been petted since as early as 3500 BC. Egyptians domesticated wild cats from Africa. These wildcats then became the most treasured pets. Cats have fascinated the literary stalwarts like T. S. Eliot who wrote a collection of poems called “Id Possum’s Book of Practical Cats”. This collection was about feline psychology and sociology. Considering the fascination for cats that we humans have, we also need to take care of them as we pet them. Cats need to be taken care of though it is a known fact that they are very hygienic. Cat care and cat health is of utmost importance if you have a pet cat. From a young age, cats get infested with external parasites. Most common of them are ticks on cats, lice, fleas, or cat mites. This infestation causes skin irritation. It is also a reason for cat illnesses.

Cat Care

There are many safe anti-parasitic treatments that can be used on a long-term basis to protect your pet cat from the external parasites. Parasites are organisms that feed on other creatures to survive. Generally, among cats they live on and feed on cat’s blood. Detecting internal ones are difficult. But, when you have a close look at the skin and fur you can detect and uncover their traces like ear mites and fleas. 



Ear mites:
They take residence in the cat’s ear canals. As they feed on them, they create an intense itching. It scratches behind her ears and violently shakes her head regularly. When you peep inside her ears, you will see dark flecks that look like coffee grounds; these are actually mites’ droppings. If you suspect ear mites in cats, contact a veterinarian.




Coccidia:
Coccidia are microscopic parasites. They live within the lining of the intestines in the cells. When they are left untreated, cats become weak and dehydrated. Coccidiosis is treatable. But, drugs do not kill these parasites, but inhibit their reproduction. Elimination of these parasites from the intestine is very slow.



Ringworm:
It is not a worm in the true sense, but rather the name for a type of fungus. This fungus is related to the fungus that causes athlete’s foot in humans. It causes discomfort, but is very contagious to cats and humans too. When left untreated, it weakens the immune system. It leaves your cat to other diseases too.

Fleas:
They are the most infamous external parasites in cats. They eat no more than a drop of blood each. A flea can cause anemia and even death in cats. It sucks the life from the cat and the fleas transmit tapeworms. Just a few cat fleas can cause discomfort in cats, especially if she is allergic to fleabites. The best way is to prevent fleas before they attack your cat.

Life Cycle of Estuarine crocodile

Introduction:

Features of Estuarine crocodile:
The Estuarine saltwater crocodile is one of the most aggressive and dangerous crocodiles. It is the world’s largest reptile the estuarine or salt-water crocodile has a broad snout with cone-shaped teeth. Its average length is five meters but males crocodile are of six to seven meters. Estuarine Crocodile have many bony scales on their neck and back, mainly grayish brown with brown and yellow sides. Their feet are webbed for swimming. It is assumed that they live up to 70 to 100 years. They have clear eyelids, which enable them to see underwater.


Feeding:
The feeding strategy of this crocodile is different; they wait very close to the water's edge and suddenly attack upon its victim in the blink of an eye. The prey of younger crocodile is smaller animals such as deep sea fishes, crabs, insects etc. Adults can also pounce and eat larger animals by drowning them, for example fish, 
sea turtles, sea birds and mammals even domestic cattle and humans.

Breeding in crocodile

Breeding
The nesting takes place in the rainy season after males fight for the female’s crocodiles. The female estuarine crocodile generally builds a nesting heap of vegetation, that contains mud and soil and it lays 40 and 60 eggs inside the heap of soil and mud. This heap raises the eggs above the water level. Female crocodile protects the nest for three months until the young crocodile comes out of the egg. After the young ones come out of the egg, the female crocodile carefully carries her young ones in her mouth and takes them to the water.

Eggs of crocodile


Female or male crocodile at birth?
Isn’t it sounding amazing?  But it’s true. The temperature of the water in which the egg is kept determines the sex of the baby crocodile. If the egg is kept at 32.6 degrees Celsius then it will be male crocodile in the same way if the water is hot or cold it will be a female crocodile.



Thermoregulation behaviors of estuarine crocodile:
Often you will see an estuarine crocodile opening its mouth.  This is because the crocodile wants to cool down, and therefore a lot of their time is spent in thermoregulation as they try to maintain their body temperature between 30 to 32 degrees Celsius as Crocodiles are regarded as cold-blooded reptile.

Their Enemies:
 These crocodiles were once hunted by humans. In many countries, like Australia, hunting of crocodile or any other sea animals is illegal, but still in many parts of Australia and in other countries they are still hunted by the hunters. In Australia, the population of these crocodiles are 100 000. Humans are not their only enemies. On the island of Sri Lanka, there are feral buffalo that destroy their habitats. On the other hand, lizards and wild pigs eat their eggs, and turtles eat the baby crocodiles.
