I need to understand the structure of sleep in cats, and how sleep is
affected by drug-induced anesthesia. My questions include:

1. Cats presumably have various sleep stages, like humans. What are these
sleep stages?

2. What are the effects of barbiturates and nitrous oxide on cats' sleep?
Do the drugs allow fluctuation between sleep states, and how long does
each state last?

If anyone can direct me to reading material on these questions, or give an
answer, I would be most grateful.
