*Lori - Hermit crab (hermit crabs are one of the most popular pets among college students).
*Leni - Turkey (turkeys are pretty dumb animals).
*Luna - Hedgehog (animals with spines are often depicted as rockstars in fiction. Plus, it kind of just seems to match her personality.)
*Luan - Hyena (although they are illegal to own in real life, Lucy already has bats. Also, yes I know that she has Gary from "Funny Business," but it would be funny if she had a hyena that Lana gave her so that way she would have someone to always laugh at her jokes.)
*Lynn - I don't know to be honest. If you have any ideas, you can reply with them.
*Lincoln - Sugar glider (this one was hard, but maybe because the sugar glider's gliding could resemble a superhero cape. Also, sugar gliders are a typical example of personal pets for children.)
*Lucy - This one is also hard because she already has bats, a new spider from "Season's Cheatings," and she had deceased spiders from "Insta-gran." Cliff is already a black cat, too. Maybe you could suggest ideas in a reply if you have any.
*Lana - She already has enough pets.
*Lola - Miniature/toy poodle (A poodle kind of fits Lola's personality, but a standard poodle sounds too big for a little girl.)
*Lisa - I'm not sure if Tentacle or the snakebird from "Blinded by Science" count. I know she has the new spider from "Season's Cheatings." If you have any ideas for a pet for Lisa, you could reply with them.
*Lily - Goldfish (since she is too young to be responsible enough to own a pet, maybe she could have a goldfish since it is an easy pet to take care of.)
*Lynn Sr. and Rita - You could technically say that they are the primary owners of Charles, Cliff, Geo, and Walt, so I'm not sure if they need any other pets.
*Hector, Rosa, Carlos, Frida, and Maria - Similar thing with the Loud parents above; you could say that they are the primary owners of Lalo and Sergio, so they don't really need any other pets. It would mainly be the kids and their own personal pets.
*Bobby - Hermit crab (maybe he could get one to match Lori and their hermit crabs could fall in love with each other or something.)
*Ronnie Anne - This one is hard. Maybe she could have her own cat that could match her rough personality? Again, if you have any ideas, you can reply with some.
*Carlotta - Miniature pony (she appears to like unicorns as shown in "The Big Chill," and it matches her personality.)
*CJ - Duck (I was originally thinking a seagull to match his interest in pirates, but I thought of a duck since it would be less exotic and more realistic than a pet seagull.)
*Carl - Chameleon (a chameleon kind of matches Carl's mischievous personality).
*Carlitos - Goldfish (same reason as Lily).
