As is the case for all disabled cats, whatever the disability, there can still be a life. It just depends on the humans because cats don’t have self-pity. They’ll just get on with it and won’t even notice that they are disabled.
Blind and deaf cats are often referred to. A cat’s acute senses are able to compensate for these cats provided we give then a secure home and a familiar routine.
Paralysed cats are different in that movement is restricted and some are incontinent. Accidents of all kinds can paralyse a cat. Examples are car accidents, being trapped in doors, being walked on (by a human), falling down from a height etc.
Other specific causes are: rodenticides such as Bromethali can cause temporary paralysis. Black widow spider bites can cause early paralysis. Coral snake bites cause paralysis but some cats survive. Rabies can cause paralysis and thereafter death. A blood clot on the brain can lead to paralysis on one side of the body. Brain injuries from which the cat recovers may leave the cat partially paralysed. A cat stroke (cerebral haemorrhage) can cause paralysis as can a disease of the spinal cord. Inherited metabolic diseases can lead to degenerative changes in the central nervous system and paralysis. Paralysis of the tail can be caused by the tail being run over by a car or the tail being caught in a door. This is quite common. These are examples.
There is a Facebook group called “Cats With Paralysis“. These are good people.
I am sure many paralysed cats are euthanised. The video shows how good life can still be. There is a hidden benefit. Your cat won’t be able to chase out of the house and get lost etc. Think about adopting a paralysed cat.
