a few yrs ago we got a kitten from my sister... he was pretty smart.. it was just me and my husband.. and we had 2 cats... well we had a cat name tiger.. and we noticed we would hear a running water sound in the bathroom sometimes.. we never thought anything about it...he would sleep in the bed with us at night.. and he would get out of bed.. and go to the bathroom. tiger would..one day i was ceaning house..and went into the bathroom..and he was sitting on the commode..he actually was useing #1 on the commode..i about fainted.. i could not beleive it.. well i called my husband... at work and of corse he said i was crazy..lol so i said lets just watch and see... so it was a while...and tiger headed to the bathroom..and he did it ..we was being sneaky..for him not to see us.. my husband was shocked... so when my family came over i told them.. i said well let me sit him up here and see what he does... he would use #1 everytime... my whole family was amazed... so we was going to move to our new huose we bought... within 2 weeks... of moving he got hit by a car and died.. it was a tragic thing...he was so special and smart.. but i like to tell my story of him ... he was a amazing animal.
