Synopsis
On Moonscar Island, a day after Moonscar's Treasure is found, the rest of Mystery Inc. stay to check for potential dangers, placing Danger signs which contains alligators, quicksand, or other hazards, along with a "Do Not Enter" sign at the cavern containing the cat idol. Inside Moonscar Mansion, as the gang is ready to rest, Shaggy accidentally broke a floorboard, and found a few notebooks, one in particular, is the history of cats, from Ancient Greece to the 21st century. The gang read the details, At nighttime, Scooby-Doo is looking up at the night sky, wandering around, unknowingly followed by a few cats. After Scooby noticed that the cats were following Him, He goes faster, Then, while running to get away from the cats, He accidentally bumps into two silhouetted figures wearing Black cloaks, who were putting some cats in cages as one enters the cave. The two figures fled after being spotted, as Scooby cautiously frees the caged cats, including the beige kitten who startled Him in the previous incident, thinking that He’d be attacked. But the cats purred around the bewildered Great Dane, as one cat, A gray-furred cat named Zanadu, led Scooby in the cave, and has Him imagine they are in the Louisiana marshes. Where six elderly cats are exploring the city for a place to spend their final weeks. the illusion ended afterward.

Back in reality, knowing that the two figures would come back, the Cats go back into hiding, except for one who is sick, as Scooby warns Shaggy and the others. At morning, as the gang checked for clues, a group of Land Developers come to the island to check the environment and check if it can be turned into a residential/commercial area. After the gang saw what's happening, a brown cat named Bunaa, placed Her paw on Scooby, bringing His mind to Ancient Egypt, but, as a Basenji, where a big group of Cats are everywhere, outnumbering the Egyptians, of course, some people (Phoenician Merchants) which Scooby thought was pronounced Venetian without being seen, smuggles handfuls of cats to the world over. Then, in 31 B.C., the cats experienced Roman life, as the illusion ended. soon, one of the developers spot some cats living there, including some rare breeds and the sick cat. But, as He called for the animal shelter, The Black Were-Cat (from the sequel) appears, destroys the phone, and scares away the worker. who calls for the animal shelter with another’s cell phone.

Afterward, a blue cat named Azrak, places Her paw on Scooby, Explaining how cats helped eradicate the Rats in medieval Europe saving many humans. Then in the 1600s, cats were sent from England to America, as they were kept not just as mousers to deal with rodents, but also as pets. After that illusion ended, a Group of straycatchers arrive, coming to capture any stray cats in the area. Scooby, thinking about the what could happen to the cats, create makeshift collars with Daphne's help, but, with only enough to make six. Eventually, one of the cloaked beings capture Scooby, and try to take Him away, but one cat attacked the being, causing Him to trip into a sinkhole. The being calls for help, as the blueish cat helped free Scooby. the cloaked being called for the other to help Him get out seconds before the developers arrived. Later, at night, Scooby sees an animal shelter worker arrive and search for any cats hiding in the island. Scooby then goes to the mansion, and quietly sees the cats hiding inside. A black cat named Aswad, who is also Azrak's mate, places His paw on Scooby, and tells Him about the Salem witch trials, which ruined the lives of people and cats accused of being witches, and that the people set out to eliminate those non-existent witches. because the senseless violence refused to stop, the Cats escaped Salem and headed all over the country. the Illusion ended.

However, the other cloaked being infiltrated the mansion as violet fog goes inside and quietly captures the cats one by one. Scooby sneaks off to warn the gang about the catnapper. However, the fog causes Him to fall asleep. Hours later, The Catnapper with all of the island cats in cages, head for their escape vehicle, a black boat. Fortunately, the cat creature attacks the catnappers, But, is caught in a cage as the catnappers intend to auction it off to the highest bidder, as a rare animal. The rest of Mystery Inc. is captured by a few of the catnappers' henchmen and they leave the island undetected. At morning, the six cats (Who were asleep in the attic) wake Scooby and explain that Mystery Inc and the rest of the cats were captured. Scooby, after learning this, falls into despair, But, formulates a plan to get to the mainland and use a big wood board as a makeshift boat. Scooby along with the six cats row to the mainland.

As night was nearing, Scooby and the Cats reach the mainland, the orange cat named Tuqaliu places His paw on Scooby. When the cats were being eliminated during the Salem witch trials, a group of people dedicated to the safety of cats hid the felines in stagecoaches and brought them to an Island, which would later be known as Moonscar Island, where they would be safe. and the illusion ended after that as Scooby and the cats find a warehouse to sleep for the night.

While imprisoned in the black cloaked beings' hideout, Mystery Inc. sees one catnapper take 16 cages, each one containing a cat, to an empty van, as a person in a trench jacket, gives money to the catnappers. Soon, Scooby and the six cats bust in and free the hostages, along with the cat creature, after being freed, chase the culprits, scaring them into the hands of the police, who arrest them and the buyer as the Cat Creature hid away. The culprits as it turned out were the two of the Animal Shelter workers, who are in fact, Erwin and Edwin Nivora, who are Co-leaders of a cat trafficking group, known for smuggling cats from all over the world, selling rare-breed ones to the highest bidder, and shaved the mixed-breed ones of their fur, making them into the Sphynx breed as their fur used as bristles for paintbrushes. along with using canisters of lavender fog to keep the cats asleep. With the criminals arrested, Scooby offers to take the cats and cat creature back to Moonscar Island, on the ferry which they all board.

On the way to the Island, the white cat named Abyad, placed Her paw on Scooby, at the time of after Moonscar and His pirates were dealt with by the Were-Cats, Six of the cats, who saw the horrendous chaos, went to the shrine, and saw visions of what will happen in the future, the cat Statue then infused an energy to the cats, gaining them immortality and to communicate with minds of others, unknown to the were-cats. After the illusion ended, the Cat Creature went to the shrine and after a few seconds, He returned to being a normal Lykoi-breed cat named Dhiib, who desired power to take His revenge on humans for what the catnappers did to His mate, who was the sick cat from earlier. As the Gang were ready to head for home, Scooby said goodbye to the cats, including Dhiib and His mate, who waved as they tended to four kittens. Then, the six cats put their paws on Scooby, and He sees a vision of the future, where cats and dogs are living together in peace, making Scooby going “Scooby-Dooby-Doo!” As the cats meow in victory.
