Cats Jumping On My Head

If asthetics are not an issue, how about installing a mesh wire door on your bedroom?

Advantages:

Keeps cats out

Let's air circulate

Disadvantages:

Makes potential sexual partners fearful

Landlord unlikely to pay for.

Maybe something uncomfortable for them to walk on in the doorway at night (unless you need to walk through it)? I don't know about cats, but for keeping dogs off of furniture, some suggested items are foil, bubble wrap, or those knobby floor mats like this.

The point is that it's a texture that feels weird or bad to them so they won't go where you put it. Maybe they would just learn to jump over but it could be worth a shot.

We used a spray bottle next to the bed and gave them a quick squirt - not in the face - in their general direction whenever they did it. it didnt' take long for them to stop the behavior and now we only need to pick up the bottle for them to know to scamper and stop.

I have the same issue. My feline Lord and Lady, being crepuscular, want breakfast at 4.30 a.m. Over the last 10 years I have gotten into the habit of getting up at 4.30, feeding them, then going back to bed. You could try an automatic feeder, but I find that His Lordship and Her Grace still like me to get up, even though the food is available.

Most people outlast their cats; cats only live about 15 or so years.

...but they are the lords of the house for their entire lives.
