A lump on cat’s back may appear as a result of injury, infection of the wound or cancer. Only a specialist could determine the accurate diagnose after all necessary examinations.
Dermatitis in Cats
A small lump on cat’s back can be caused by skin diseases. The owners of haired cats face this problem especially often. Inflammation of the epidermis is accompanied by itching, the animal combs the skin and this leads to the formation of a seal. Causes of dermatitis:
- Allergic reaction;
- Fungal infection;
In response to contact of an irritant with the skin an inflammation may appear. Most often this occurs due to contact with household chemicals, but some drugs for antiparasitic treatment can also cause an allergic reaction. Inflammation of the epidermis can be triggered by fungus. In this case, the skin begins to peel and itch, and the cat combs the affected area leading to the formation of seals. In long-haired animals the cause of the formation of lumps can be vermin, primarily ticks. The accumulation of eggs of the subcutaneous mite can be similar to a lump on cat’s back near tail.
Wounds and Abscesses
If there is hard lump on cat’s back near spine, you should carefully examine the skin of the animal. The probable cause of the formation of lumps on the back is an abscess. It is a cavity filled with pus, which is formed due to infection of wounds and minor skin lesions. An abscess can appear at the site of the impact, in elderly animals the formation of such lumps is possible against the background of hypothermia. This condition causes discomfort to the animal, which becomes noticeable because of the change in the pet’s behavior. Touching the abscess causes pain, so the cat does not want to be taken in arms and avoids any contact. The skin around the abscess becomes hot, redness is possible. Upon this, the pet feels weak, it may refuse to eat.
Note!Quite often cats are trying to get rid of lumps on their own, trying to comb the skin in the affected area. This should not be allowed, since the opening of the abscess can lead to infection of the entire body when the purulent masses enter the mucous membranes of the animal.
Abscesses should be removed surgically. The whole procedure takes no more than 15 minutes and is performed under anesthesia. The vet opens the purulent cavity with a scalpel, cleans its contents, and then carries out antiseptic treatment. Sometimes the treatment includes antibiotic therapy.
Soft Lumps in Animals
A soft lump on the cat’s back is a lipoma. It is quite easy to distinguish it from abscess and other tumors, it is enough to grab the lump with two fingers. A lipoma, or fatty tumor will easily roll beneath the skin, and the cat will not feel uncomfortable. The formation of fatty tumors is due to the accumulation of sebum. They form a soft capsule, which is shaped like a ball. Lipomas themselves are absolutely not dangerous and do not cause discomfort to cats. Their appearance is caused by endocrine disorders or natural aging of the pet. Nevertheless, veterinarians recommend to remove lipomas, as there is a risk of degeneration of benign consolidation into malignant neoplasm.
Tumors in Cats
The tumor on the back of a cat can be both benign and malignant. It is impossible to distinguish one from the other by sight. To determine the diagnosis a comprehensive examination by a veterinarian should be performed, which includes:
- X-rays of the back.
- Blood test.
If cancer is suspected, a biopsy is carried out. During this procedure, the lump is pierced with a special needle, into which small fragments of tissue are collected. The resulting material is then sent to the laboratory for histological analysis, which allows to determine the type of cells. After confirmation of the diagnosis, surgical removal of the tumor is carried out. In benign tumors, additional drug therapy is not required, in malignant processes chemotherapy is carried out. In most cases tumors and lipomas appear in animals older than 10 years. This is due to the natural aging of the body, slowing metabolism and the development of chronic diseases. According to statistics, lipomas are more common in animals with overweight and endocrine disorders.
Only a vet can accurately determine the type of tumor. The tumor will not resolve itself, so having noticed the lump you should take the animal to the clinic as soon as possible.
