I think what you're trying to say Alekto is that they're not of a very high resolution so the image isn't as good a quality as it can be~
But I agree, your photos are beautiful~
You got some lovely shots of those cats! I think you probably just need a better quality camera, one with macro mode so you can take these detailed close ups. And when you upload them make sure they're of at least 75ppi, if you just want to view it on a screen, if you want to print them out at all make sur eit's at least 200ppi or more. They'll show up much better quality and try save the imaged as a .png file.
You've got a brilliant eye for photography though, keep it up!
