enter the words as you see them. you can repeat some of the words as phrases.
cat,black,black cat,alley cat,etc cat,feline,kitty, and so on, all of those are ok. put your name down, add a location if its a city shot, mention colors, items that stick out, the season. add a plural if you think it needs it. it only wastes space but it may be that one ahead of someone else's work because you have that word that matches better.
