If you’ve been raising a bunch of pets in Roblox’s Pet Simulator X , we’re here to help you maximize your profit by utilizing some of the best strategies and fuse methods available in the game mode. By the time you’re done with this guide, you’ll be swimming in coins and your mythical pets.
How to Farm Rainbow Coins for the Grind
Before you can start the fusion process, you will want to grab as many rainbow coins as possible to buy the Paw Egg, which costs a total of 34.4 million rainbow coins.
- First, press the teleport button on the left side of your screen.
- Find “Hacker Portal”.
- Teleport here, and enter the portal by pressing E.
Portal Teleporting Spot - You’ll end up in the void. If you’re here for the first time, complete the three quests.
- After completion, simply follow the yellow bridge and use the cannon to go to the cat world.
Cat World - Once you’re at the cat world, go in the opposite direction from the eggs.
- You’ll see a chest in the distance.
- To get to it, beat all the areas in between.
Put on your best pets - Put on the best pets that you have with rainbow enchantments.
- Activate all of your boosts.
- Set up an auto clicker and leave it overnight at the chest.
- You should gain a decent amount of rainbow coins farmed while you AFK.
The Ultimate Strategy for Fusion in Pet Simulator X Cat World
For the initial stage of this process, we’ll go for the cheaper egg, as discussed above. There’s no point in going for an expensive variant, as we’ll create rarer versions through fusing.
Turn On Auto Hatch for Paw Egg
Once you have enough money, you can begin the hatching process. This will get us enough pets to ascertain our chances for fusion.
Now you have a bunch of relatively common pets; it’s time to start using all the available pets to make even rarer ones!
Upgrade Your Pets Before Fusion
We don’t want to complete the fusion process without having access to a large number of pets while also ensuring quality. To kick things off, we will take all the pets we just obtained from the Paw Egg and take them to the Gold Machine at ‘Shop’ in the normal spawn world. Add six pets for a 100% chance at a golden pet. Repeat this until you run out of normal pets.

Now, go to the Rainbow Machine. Similarly, we will try to achieve a 100% chance of getting a rainbow pet. But if you can’t, that’s fine; just do it for as many as you can!

Time to Fuse
Now that we have the rainbow pets in our inventory, we have to make our way to making a mythical pet. Before we do that, however, we’re going to want to get our hands on rich cats.
- Start by fusing three propeller cats, which will give you either a safety or garden cat.
- Once you have a bunch of safety and garden cats, combine four at a time each of these to get hydra cats.
- Fuse three hydra cats to get a hoverboard cat.
- Fuse the three hoverboard cats, which should give you a rainbow-rich cat.
Well, now that you have your hands on a rare commodity, which is the rich cat, you can go ahead and trade it for a mythical helicopter cat. Why are people going to trade you their mythical pet for your rich cat?
The rich cat (rainbow) is worth 85 million gems, and the mythical helicopter cat (normal rarity) is worth 55 million. That means, whoever you’re trading with is making a decent amount of profit.
While they might be making a profit, keep in mind that the dark matter mythical helicopter cat is worth 2.8 billion.
How to Find Someone to Trade With
By following the aforementioned steps, you’ll be able to start finding trades with other people who are willing to lose their mythical helicopter cat. To do so, head to the trading plaza, which can be found at the ‘Shop’ teleport in the Spawn World.

You can also try and hop into different lobbies. Ask if anybody’s interested in your trade every time you’re in a new lobby, and move to the next one if you can’t find any interested parties.
Feel free to join communities outside of Roblox as well, such as discord or Reddit communities to find people playing the game and see if the both of you can come to a mutual agreement regarding the trade.
Conclusion
Congratulations, you’ve finally landed yourself a huge amount of money through this method. You might want to step on it as early as you can to farm mythicals and sell their dark matter variants for maximum profit.
