You could always shorten it to just plain April. Then you could (officially) call her J. P. April...
You know - short for Just Plain April...
I don’t like April for a cat’s name, especially this one. Some names I have considered...Spot, Snowball, Speck, Spectre, Whitewash, and Boomerang. The last one in my favorite. Of course, it will no doubt be shortened to Boomer, but hay...it could be worse...like JP April...
