Unicorn - so pretty, so sparkly, so pointy!
One that takes complete care of itself but is still fluffy and warm. So i guess a hot water bottle.
None - hard enough looking after kids without some other parisitic being in the house trying to take up the little time I have!
a dog that can use the toilet.. a bit like mr Jinks in meet the Fockers
A dog breed that likes to be active and outdoors during the day and home on the sofa for cuddles in the evening.
