Yikes! Hopefully it was easily to get out of his coat! When my parents were first dating, she had a kitten whose name was either Crankcase, or Friendkitty, depending on who you asked, because as a kitten, he fell into a pan of crankcase oil, and not even his cat mother would go anywhere near him! After a couple scrubbings down by the humans in t5he family, he appeared to be okay, but it was never determined whether the apparent dim-wittedness was a result of the incident or caused by it! He had a habit of assuming everyone loved him (hence Friend-kitty), even their big old Mastiff mix who did NOT like cats, and preferred chasing them. This one would wend around his legs, purring, much to his dismay!

Glad your kitty is okay, hope it came off the floor as readily, too!
