A dog house, because a cat house has no woof!
To scare off Cat burglars!
They prefer a cat-alogue.
Freeze your dog and then take an angle grinder and use it on your dog and it Will say meeeeeow. Dunk your cat in gasoline and light it on fire and it Will say woof
Pour some gasoline on it and WOOF!
None because ice cream doesn't have bones.
