Okay, I finally took a couple pics. I actually got myself in trouble last night as I planned to take the pic, and then get back to the computer to post it. My cute kitty joined me, and after taking the pics, I fell asleep, without my mask on. I only put it on for the pics, so I had not actually fitted it perfectly or gotten ready for bed. So, I woke up 5 hours later and realized my mistake. And I have been coughing for almost 2 weeks now, so I have already been having a tough time sleeping in general and keeping the mask on all night.
I have the Quattro FX which I really like. I am definitely a mouth breather, so I had to go with a full face. I really like not having the forehead thing to deal with. Teh mask looks larger than it feels. I was actually surprised at how large it looks in the photos. It doesn't feel that large at all. I also like how easy it comes off in a hurry. Just hit the two quick release buckles and off it comes. Now that I have the small size headgear, I rarely have to adjust the straps. I was really messing with the straps on the medium headgear, several times a night.
I have no problems sleeping on my side. I actually do that almost exclusively now. And I have no problems with the mask and my pillows.
As you can see, my kitty has no problem with my mask at all. On rare occasions, I have blown air on her, but normally the exhaust is up above her, so no big deal. She was still in the same place when I woke up 5 hours later. Sometimes, my hose goes across the top of her, and sometimes I wake up, and the hose is under her. She's less than 8 lbs, so it doesn't affect my airflow. It just makes it a little harder for me to get up to go to the bathroom. The rule is, do not disturb the kitty
As much as I would love my other cat to sleep up closer to me (he rarely sleeps close enough for me to reach him), I can see where he would be a problem. Once, he was in range, and he thought the hose was a kicker toy. Um, NO!!!! And if he were ever to sit on it, I would definitely notice a loss of pressure. He weighs 18 lbs.

Who would have thought it would be this challenging to sleep and breathe at the same time?
