On Tuesday afternoon my two year old cat was spayed.  I left her in
her carrier per the vet's directions and she flipped violently for
about an hour.  After I couldn't stand it anymore I just held her.  A
few hours later she was fine, playing like normal, eating normally.
Last night she fell asleep and it was extreamly difficult to wake her.
 She is also not sleeping in her normal postions and does not move at
all while sleeping.  Today she did not get off the bed until around
5:00pm when I put her in her litter box and she went.  Since then she
still just falls asleep while sitting up and has no interest in eating
or drinking.  I did get her to eat a few spoon fulls of yogurt (her
fav treat) and have using an irrigation syringe to give her water
every few hours.  I am worried that she is sleeping too heavily and
too much.  Has anyone else had this experience???
