I have a cat that acts like a dog.. (But it doesn't bark.. It sorta yips... o.o) named Spook.. (He looks like a cat that was spooked by a very scary dog.. Hae has bits of black on his paws like a boot) He sits, plays dead, begs, lies down, speaks "Mreow", and is VERY sanitary.. My dog Casper, (A very adorable Beagle) is an inside dog and get along well with Spook.. He does all the same things except meow.. and is very clean.. (My brother tought him to wipe his paws on the mat.. >>) He is very lovable.. ^^ They both drink Filtered Tap Water...
