If the cat has a swollen neck after a recent collision with hard surfaces or falling from a height, then there is a greater likelihood of developing hematoma and bruising. Things are more complicated with stings of stinging insects, so there is always a risk of suffocation due to severe edema. Even more carefully master need to be of adults individuals, who, after the age of 10 years, have a risk of neoplasms of benign and malignant nature, requiring timely detection and removal (if necessary).
A Detailed Description of the Possible Causes
If the cat’s neck is swollen after taking any medications, then this reaction cannot be ignored, as an allergy to medications is considered very dangerous and can cost a pet’s life. It is bad when this symptom appeared in an animal after a walk along the street and the master has only to guess what could have caused it to occur. Therefore, we list the most common options that can lead to varying severity of edema of the neck in cats:
- Hematoma. A distinctive feature of the hematoma is the color and size of the formation. In appearance, it seems that the cat’s neck is swollen, but felt it on a touch can be understood that this is a bump, inside which is concentrated some liquid (baked blood). For large hematomas, an incision is made to pump out the lymphatic fluid. If necessary, the wound is drained, because the fluid can come out within 2-3 weeks.
- An injection. If the pet was given any injections to the withers, then there is always a risk of formation of seromas, abscesses and hematomas in this area. It may seem that the cat’s neck is swollen, but touching this area, it becomes clear that the problem lies in the neoplasm, which can be hard to the touch and cause pain in the animal. Abscesses are usually opened and cleaned from pus, drainage is applied to drain the fluid during healing. Hematomas often resolve on their own within 2-3 days, provided that their size is not larger than a walnut.
- Insects bites. First of all, we are interested in stinging of insects, after which the cat’s neck can not only swell, but also appear a strong reddening of the skin and terrible itching. In the most scenarios, animals suffer from bites of wasps and bees, less often bumblebees and hornets. In many ocasions, pets do not even leave the boundaries of their housing, unfortunately, wasps often fly into open windows even in noisy mega-cities. On the one hand, the stings of stinging insects do not pose a significant danger to the health of the animal, but on the other hand, the neck, larynx and tongue can in rare cases cause suffocation. Therefore, with severe edema, it is better to immediately take the pet to the veterinarian, as this can cost animal’s life. Small swelling subsides on their own during the day, you can reduce the symptoms with the help of antihistamines.
- Eosinophilic granulomas. It is considered an independent disease, but many veterinarians attribute it to one of the types of allergies. When lesions form on the mucosa, they look like bleeding ulcers, skin rashes are more like bites of flies or gadflies. A cat’s neck can swell after scratching with a granuloma to the blood. Also, in places of lesions, fur may fall out and the skin becomes inflamed. Small, solitary formations can be observed and not apply any therapeutic measures, as they often pass on their own. With multiple lesions, hormone therapy can be used for a long period. To make a diagnosis, cytology and histology of cells taken from lesions are performed.
infection. Even a tiny wound can provoke severe swelling if an
infection gets into it and the inflammatory process begins. A cat’s
neck can swell after a fight in which she received deep scratches
from claws or bites from its teeth. Small wounds usually heal
without any consequences within 1-2 days, but if swelling, redness
and traces of pus appear, then this may indicate the development of
an inflammatory process. In difficult cases, you have to open the
wound and clean it from pus and lymph fluid. Anti-inflammatory and
regenerative ointments are used for healing. Also, antibiotics are
prescribed at the discretion of the veterinarian. The absence of pus
and redness can be considered a complete recovery, while healing the
wound becomes covered with a crust, which itself disappears. It is
recommended not to allow the pet to scratch the lesions, because
this can not only delay the healing process, but also join a
