I lift Sugar, Lacey and Ozzy on my bed each night as part of my preparations for bed. Not to results in whines, whimpers, and all out barking! Then I have to lift them down when they want a drink, back up when they have finished.

Marlin has stairs so he can come and go on Dad's bed day or night. However, he DOES require a cheering squad to get UP the stairs, so the whole house knows if he got down for any reason during the night (water, security patrol, etc.)

The cats come and go. In general, Crystal sleeps on Dad's bed, the other 10 spend the night coming and going from my bed. This has been going on for over 10 years, not sure I could sleep on a stable bed! And of course, Tommy loves TOES, so I sometimes get woken up with nips.

Marlin and Crystal seem to have cornered Dad's bed for themselves; sometimes they allow Dad in, but the other pets are sternly turned away.
