The information included in this article appears thoughout the entire 39 Clues universe.
Saladin is an Egyptian Mau who previously belonged to Grace Cahill before her death. The Mau is currently with Amy and Dan Cahill, taken care of mainly by their au pair, Nellie Gomez. Grace Cahill trained him to sneak into buildings too dangerous for her to enter, like the Lucian stronghold in Moscow. He is also trained to wear a camera on his back for surveillance. Saladin was also trained to snorkel, said in The Black Book of Buried Secrets. During the Clue hunt, he accompanied Amy Cahill, Dan Cahill, and Nellie Gomez on the search for the 39 Clues. In part of the Maze of Bones, he was temporarily taken care of by William McIntyre when Amy thought it might get too dangerous for Saladin, but he was returned later on because Mr. McIntyre could not handle him. Later, the Cahills suspected Alistair Oh of putting a tracking device between his neck and collar, but it was found out that Mr. McIntyre and Fiske Cahill actually were the ones keeping tabs on them. He is also a very picky eater and will only eat red snapper (his favorite), but occasionally barramundi (as seen in the 6th book, In Too Deep), hummus (as seen in Beyond the Grave), Russian caviar (as seen in The Viper's Nest), sushi (as seen in Card 33), and occasionally cat food, like normal cats. In Outbreak Saladin is a great help in saving Cuba and the world. Saladin helps manufacturer the cure for the genetically modified goat pox.
In the book Saladin first appears next to Grace Cahill a while before she died. After that, he was found along with Grace's jewelery box in her secret library by Amy and Dan. After that incident, they took him with them in the hunt. He was later left in the care of Mr. McIntyre.
Saladin is on a hunger strike. He appears with Nellie and the two Cahill kids (Dan and Amy) while they search for the next Clue in Venice, Tungsten. Saladin also reluctantly acts as "watch-cat" when Amy and Dan are in Disco Volante. Nellie notices him scratching the area around his collar and takes him to the vet while Amy and Dan explore the Salzburg Catacombs. After they meet up, Nellie tells them that the vet found a tracking device in the cat's collar, placed by William McIntyre during the Mau's time with him. At the end of the book, Nellie gets Saladin to eat cat food, something of an accomplishment to her.
When Dan and Amy escaped with Alistair Oh, Nellie is left in charge of the cat, and Nellie later forms a temporary alliance with the Kabras. While on the way to help Dan and Amy, the Cahill children discover Natalie Kabra is highly allergic to cats while in the car with Saladin, screaming that she hates cats.
Shep feeds him barramundi and Saladin likes it.
Saladin's taste grows for Russian caviar. Dan imitates another Mau, hoping to draw Saladin. Next, Dan saves him from drowning, earning Dan many scratches, but if Dan had not gone out to get Saladin, the cat would be dead. Later he is with Nellie and Amy as they wait for Dan outside a bookstore. Dan comments on how amazing it was that so much anger could be contained in a "mrrp."
Saladin embarks on a plane and has to sit in the cargo area because of the Cahill kids' allergic neighbor passenger. He appears in the cat carrier with Amy, Dan and Nellie. After Dan and Amy's argument we find him in the Great Wall (China) and jumping down from it. Near the end of the book, he shows up at Mount Everest along with Dan and Amy, who are about to go in the A-Star to fly to the peak of Mount Everest get the Janus Serum (although Amy ends up saving Ian instead of the serum). It is learned that Saladin is neutered to keep him from making cat babies.
Saladin is held hostage by The Man in Black/Fiske Cahill so that Amy and Dan will open up a box to get the next Clue, which turns out to be Mace. Dan and Amy also passed the test to gain full Madrigal status.
Saladin was on the branch which Dan was on to spy Evan and Amy. He eventually breaks the branch because of his weight. He is next found on an airport where Dan tells him not to be easy on Ian. This could be why he messes with Ian.
Saladin does not appear quite often in this book, but it is shown that Saladin was bonding with Evan Tolliver. Evan also said that Saladin is one of the reasons why Evan likes Amy.
Saladin is giving Ian a hard time. Ian remarks that Saladin's "mrp" means "I-hate-you-with-all-my-heart". To Amy and Dan, his mrrp means a lot.
Saladin scratched Ian's face causing injury. Ian calls Saladin a "Demonic cat" due to this and locks the cat in the kitchen. Evan later freed the cat by cutting through the kitchen as a shortcut to the guesthouse.
In Worlds Collide, Dan, the Cahills, and Hystorians, and Greencloaks are partying in the Cahill Command Center, with Saladin as the DJ.
Saladin has his own CliqueMe profile. It is much theorized that this was created by Amy, due to the similarities and comments on the profile. His favorite books match Amy's favorite books, it says that he likes hanging out in libraries with cool humans, like Amy, and in the comments, he says, "Dan, you're such a dweeb!" which Amy frequently says in the books. Even Dan notes that he is typing like Amy. Dan comments that Saladin seems to be posessed, except by "bookworms instead of aliens".
Saladin appears in:
- Saladin, in Outbreak, seems to think he can save the world...
- In addition to that he can understand humans.
- Saladin is wanted by the US government and is thought to be dead.
- Saladin is the only being on earth to carry a genetically modified version of goat pox and is also immune to it.
- Saladin's name is most likely based off of Salah al-Din, known to the West as Saladin. He was the founder of the Ayybuid State, and although he lived before the Cahills, he has very Madrigal-like qualities, as he was a great peacemaker. He had defeated the oppressive Fatimids, and he created peace between the Muslims and the Crusaders over Jerusalem. He also came from Egypt, just like the cat breed that Saladin is.
