Boy Cat Names That Start With L

Laureate

Sour or sweet? Enough like Lennon, Leonard, and Clement to work, or best left in the fruit basket? That's up to you to decide, but Lemon has been appearing in the US charts for boys since the 1880s. 
 
Currently more popular for girls (given to 50 in 2021, and 29 in a more recent year), Lemon has been out of the charts for boys since the 90s, but that's not to say it won't ever return, given the interest in wild word names in recent years.
 
One thing to bear in mind is that Lemon is sometimes used as a slang term with a couple of meanings. It may refer to: a defective and faulty car or gadget; to an unhelpful person who won't take action (as in, standing there like a lemon); and, in a more niche (and perhaps slightly outdated?) way, for explicit content in fanfiction. Make of that what you will.
 
Lemuel, Lemoine, and Lonan might be similar sounding options,
