To develop the "eye" you'll need to see the whole frame first. Posted photograph indicates that you have been focused on the center only (main subject) ignoring the corners and allowing for all that irrelevant grass area to actually fill the frame and swallow the poor cat! (Also, post processing could have been better as well, and drop that text, it's hard to see anything else.)
Look everywhere and try to criss-cross the frame in the viewfinder while composing an image. Check corners, follow lines, see how foreground and background interacts, and move the camera slightly and/or move around the subject to exclude distracting details, allow some line to extend and breathe, for patterns and colors to balance, for perspective to change and objects interact and align, and so on. At one point you will suddenly realize that your brain is telling you "that's it!" and you will really
feel that everything is balanced and stable. Like everything in the frame is glued together and forms the unbreakable whole. Then, and only then, press the shutter release button.
