Well if Tucker is anything like Murphy, he sure won't learn the first time. Murphy is constantly following the cats around pestering them because he wants them to play. Hopefully this close call for Tucker will teach him not to annoy the kitty, lol.
No worries...my kitty is 16 years old and in kidney failure (and on home IV fluids every other day). He actually tolerates a lot from Tucker. They are both able to stand side by side these days and not attack each other. Tucker has learned (well...most of the time anyways) his limits with Ace (my 16 year old cat). My other cat (Sammy-who is 17) doesn't tolerate him AT ALL and I don't allow them around each other.
