There is no evidence of the existence of cat/human diseases that can infect plants or plant diseases that can infect cats/humans. Plants and animals are enormously different biologically. A pathogen that has evolved to infect one is very unlikely to to be capable of infecting the other. It's just as likely as the existence of a nobel prize winning physicist who is also the heavyweight boxing champion of the world.
