In the first photo I think it is a pity that your cat is in the shadows whereas the background is in the sun. Something does not feel quite right here what with the distribution of light.
In the second it is a pity that a stripe of shadow fell across your cat's eyes right in the moment of you taking the photo. It looks like only a short time later its eyes would have been in the sun, catching that light.
The third is nicest, a) because the grass is so wonderfully green (and I just love that colour, which is news to most on here, I am sure :greenpbl: ), and b) because your cat is in the sun.
The background feels a bit "cluttered" with so much yet to be seen and recognised, and it takes away from your subject. The way you took this photo also places your cat's eyes into the very centre of your frame.
Both things could be changed by a simple crop. If this were mine, I'd crop in from the left so the neighbours' car and house would disappear completely, preferably also what looks like a blue trashbag. And then I'd crop in from above so the dangling light fixtures would also almost totally disappear, watch for your cat's ears, though, don't crop those!
But hang on! My "scroll-crop" shows me that then your cat has no more room to look into within the frame. Hmph ... :scratch: ... that is not good, either. Since it is gazing in that direction, there should be room enough for it to gaze into.
Well, it is up to you if you want to take up my cropping ideas (the trashbag need not oh-so-necessarily go!) and what you come up with for yourself. Maybe you also are all pleased with the photo as it is?
