How does Siamese cat suffer from sarcoptic mite and ear mite disease

       Sarcoptes scabies is a contagious skin disease caused by Sarcoptes scabies. The sick cats have severe itching and eczema like changes. In cats, there is a highly infectious ear mite disease, which first shows symptoms from the head and auricle. It is caused by the ear mites. The ear mite is a kind of scabies.

       The characteristics and spread of the disease were as follows

       The body of Sarcoptes scabies is nearly round or oval, and the dorsal surface is convex, milky white or light yellow. The size of female mite was 0.3-0.5 ¡Á 0.25-0.4mm, and that of male was 0.2-0.3 ¡Á 0.15-0.2mm. The jaw body is short and located at the front; the claw like claw with small teeth on the tip is suitable for biting the cuticle tissue of host skin. The whiskers are divided into three segments. No eyes and valves. On the back of the body, there are transverse wavy striations and rows of scaly spines. There are several pairs of rod-shaped setae and long bristles in the posterior half of the body. The abdomen is smooth with only a few setae and 4 pairs of feet. The foot is short and thick, divided into 5 segments, showing a conical shape. The distance between the first two pairs of feet and the last two pairs of feet is larger, and there are horny processes at the base of the feet. Both male and female mites have long stalked claw pads at the ends of the first two pairs of feet, which are called ambulacra, which are sensitive parts of sensation. The ends of the last two pairs of feet are different in male and female. The female has long setae, while the fourth pair of feet of male has suction pad. The ovipositing foramen of female mites are located in the center before the last two pairs of feet, and the external genitalia of male mites is located slightly behind the fourth pair of feet. In both cases, the anus is located in the middle of the posterior edge of the body.

       Symptoms and diagnosis:

       This disease is a contact infectious parasitic disease, so contact with sick cats, or sharing of combing and bathing tools between sick cats and healthy cats, and cross contact of breeders are the causes of the disease.

       Scabies mainly occurs in the head (bridge of the nose, orbit, auricle and root of the ear), sometimes it can also occur in the chest, under the abdomen, armpit, the inner thigh and the root of the tail, etc. when serious, it can affect the whole body. The cat is itchy and restless, scratching the affected part with the forelimb, biting the affected part with the dog or rubbing the affected part on the surrounding objects. The affected part showed flushing, with rash, small nodules, subcutaneous tissue thickening, the formation of scales, the affected part is often lack of hair. Severe scratching and gnawing can cause local infection, suppuration, external auditory canal inflammation and local bleeding. Acariasis caused by ear mites or small ear mites, first occurs in the ear, with severe itching. The affected cat constantly shakes its ear and shakes its head. The ear is often scratched and bleeding, and is infected with purulent mites, forming abscess type acariasis. In order to distinguish from alopecia and other diseases, it is better to scrape the skin scraps at the junction of the diseased and healthy parts of the cat, dissolve them with 10% caustic soda solution, and then observe the scabies under a low power microscope.


       It is one of the most important preventive measures to keep the environment clean and utensils clean. Cats should not be allowed to go out at will, and the sick cats should be isolated and treated in time. It is necessary to comb and bathe cats on time, disinfect cat houses and cat utensils regularly, strengthen feeding management, and enhance cats’ physique and disease resistance. First of all, the affected part of the sick cat and its surrounding areas should be thoroughly sheared, soaked and washed with warm soapy water to remove dirt and scab. Then, 0.5% trichlorfon aqueous solution or ointment should be applied locally. When smearing, it should be rubbed vigorously to make the drug penetrate into the skin. Repeat once every 5-7 days. Generally, it can be cured after 2-3 times. However, the surface area of animals should not be smeared more than 1 / 3 each time to prevent poisoning. 0.1% phoxim emulsion, 0.1% dimethacrylate solution and Mieshaling were effective.

       Disease prevention:

       Regular deworming

       Because some intestinal parasites (such as Ascaris lumbricoides) are ingested or transmitted by other organisms (such as fleas, mosquitoes, etc.), and the kittens in the same nest like to lick each other, so the young cats must be treated regularly. Adult cats can’t help but contact the secretions or excreta left by other dogs on the grass with their tongue when they make social guidance and go to meet friends by smell. In this way, they will be infected with parasites. Therefore, adult cats should be treated regularly.

       The common internal parasites include Ascaris lumbricoides, tapeworms, coccidia, hookworm, trichomonas, Giardia, scorchera and heartworm. The main ectoparasites are Demodex, scabies, urticaria, fleas and lice.

       Borschnet suggests that you should stop the interference of parasites on the growth and development of young cats and prevent the occurrence of parasitic enteritis from 10 weeks old. The choice of anthelmintic should be very scientific. It is not exactly the same as human’s anthelmintic, and the dose is not the same. Therefore, you should choose a regular pet hospital. Don’t let “quack doctor” affect the baby’s health.
