I had to put my cat down years ago because of seizures. He got better for 2 full years with some natural treatments, then one day he went into a seizure that last 3 hours and I knew he was never going to come out of it. I took him to my friend who is a vet and he put my cat down, SO SAD! As for cancer, I give my dog 1-2 apricot seeds a day to prevent it, I have seen animals and people cured of their cancers from using the seeds, they really work. I cant remember the site for the seeds but I think their is a link on http://www.blacksalveinfo.com There is also a link there for black salve and bloodroot paste for Vets too, work very well! Hang in there, I know how hard it is to lose a loved one like a cat or dog :(
