I've a waste disposal unit at home, so in a bag, open the chute, and away it goes!  Never to be seen again (as I discovered once when I erroneously threw my neighbour's keys down there with her kittens' poop bag!  aaaaah!  it was a Sunday - kittens were on their own, and one was being bottle fed - and I had to get into the area where the units all come down...  and find the poop bag, and keys.
 
I did!  The other half still hasn't forgiven me that one!!!
 
 
Horrible to be weighed fully dressed, having eaten and drunk.  My darned GP does it to me each time!
