sphynx knowledge

So, as a profession I'm a nail technician, and of course I love getting onto the subject of animals, and have had many reactions to little Lucifer, he's become abit famous with my clientele and they always ask how he is! I have one lovely lady who works in a cat shelter, and I like to ask her...

Just a few questions to check the little ones okay! He has the tendency to sneeze..a lot! I know that dust is more likely to irratate them, I was just wondering if this is normal? Slightly sloppy poos from time to time, I did read somewhere they have some softer ones, but just wanted to double...
