Can Occur with the Following Diseases:

Basics and possible causes

Sudden paralysis in cats can be caused by various factors that may have neurological, muscular, or vascular origins. One of the most common causes is a problem in the central nervous systemThe CNS (central nervous system) consists of the brain and spinal cord. It is responsible for processing information and controls most functions of the body and behavior., especially in the spinal cordThe spinal cord is a long, narrow bundle of nerve tissue located in the spinal canal of the vertebral column. It is part of the central nervous system and transmits nerve impulses between the brain and body. or brain. Injuries, Inflammatory conditions, or tumors can put pressure on the nervous system, causing paralysisParalysis is the complete loss of muscle activity in one or more areas of the body, which can lead to immobility and loss of sensation. Paralysis can be caused by injuries, illnesses, or disorders of the nervous system..

Vascular causes are also common. For example, a thromboembolic event, such as aortic thromboembolismThromboembolism is the blockage of a blood vessel by a blood clot (thrombus) that has formed in one place in the circulatory system and then moved to another location. This can lead to serious complications, such as a stroke or pulmonary embolism. (ATE), can occur. This is a condition in which a blood clot blocks the blood supply to the hind legs, which can lead to sudden paralysisParalysis is the complete loss of muscle activity in one or more areas of the body, which can lead to immobility and loss of sensation.

Parasitic infections can affect the digestive tract, skin, and other organ systems. infestations, such as those caused by Toxoplasma or Neospora, can also affect the nervous system and lead to paralysisParalysis is the complete loss of muscle activity in one or more areas of the body, which can lead to immobility and loss of sensation. Paralysis can be caused by injuries, illnesses, or disorders of the nervous system..

Muscular causes include conditions such as myasthenia gravis, an autoimmune disease that impairs communication between nerves and muscles, and polymyositis, an Inflammatory condition of the muscles.

Typical accompanying symptoms

Difficulty walking: The cat shows an unsteady gait, drags one or more legs, or cannot walk at all.
Weakness in the limbs or loss of muscle strength: The cat may have difficulty getting up or moving, even when motivated to do so.
Loss of control over the bladder or bowel: In severe cases, the cat can no longer control its bladder or bowel, leading to incontinenceIncontinence refers to the inability to voluntarily control urine or stool, leading to involuntary loss. There are various forms, including urinary incontinence and fecal incontinence, which can be caused by different factors..
Pain: The cat shows signs of pain, such as frequent meowing, restlessness, or defensive reactions when touching certain parts of the body.
Behavioral changes: The cat may become apathetic, aggressive, or anxious, indicating discomfort or pain.
Swelling or discoloration: Especially in vascular causes, there may be swelling or bluish discoloration of the affected body parts.

When to visit the vet?
