My cat has spreading paralysis after a leg wound. What's wrong?
Hello Bobby. I am sorry that Becky is so sick. From your description I would be worried about a few possible causes. If the problem started as a wound from the leg, I would be very concerned about an infection that is spreading. Also, cats can get blood clots that stop the blood flow to the back legs, so if the paralysis is just in the back legs this could be the cause as well. If this is a 'nerve problem', and it is spreading, then it isn't typical of nerve disease. I would be very worried about Becky's chances at survival based on what you are describing. I would talk to your vet about infections and if that seems to be the cause, and pursue bloodwork. You can test for blood flow to the back legs by checking the glucose in the front legs vs. the back legs, and also feel if the back legs are cold to the touch. If they are cold and if the glucose in the back legs is less than that of the front legs, then likely a blood clot to the back legs is present, and you should seriously consider euthanasia as it is a very painful and untreatable condition. If the legs are warm and there is good blood flow, and no infection seems to be present, and Becky seems happy and comfortable otherwise (eating/drinking, no crying, not painful), you can try acupuncture however there aren't good scientific studies about the efficacy of this. I would suggest massaging and frequent range of motion of the back legs, and seeing if return of function occurs. Also, nursing care to ensure Becky is able to urinate and defecate is very important. This is very complicated and without intensive care I worry for Becky's quality of life. You should re-assess with your veterinarian and discuss these options.
