Shaking legs in an otherwise healthy feline is rather uncommon, so when you witness the sight, you might be alarmed. This syndrome can be brought on by sources from arthritis to poisoning and typically calls for veterinarian attention.
Arthritis can be caused by trauma, infections, disorders of the immune system and even developmental disorders. When a cat has arthritis, and leg stiffness or favoring occurs, shaking limbs can follow.
Feline Thromboembolic Disease
According to the Georgia Veterinarian Specialists, feline thromboembolic disease is one of the most difficult and frustrating diseases for veterinarians. This condition, occurring secondary to severe heart disease, causes cats to present acute onset of rear limb dysfunction and can display shaking limbs.
Seizures in cats can be induced by a drug overdose, trauma to the brain and metabolic disorders. These spastic episodes, depending on the intensity, can result in symptoms that include shaking one leg to shaking the entire body, including all legs.
A severe cold, which can include frequent sneezing, nasal drainage, coughing, weakness, high fever and shaking legs, can cause concern for a feline owner. If these conditions are noticed, advice should be sought immediately from a veterinarian.
There are a number of items in and around your home that can be hazardous to the health of your cat, even poisoning them, which can lead to symptoms including shaking legs. According to the Cat Fanciers' Association, harmful substances can be found in antifreeze, some flea products, plants and potpourri.
