Mutations in Catch and Tame on Roblox are the single biggest lever you have for increasing a pet's per-second income. A mutated pet looks different, earns more money, and — in some cases — grants bonus perks like extra breed luck or free Lucky Blocks. The catch is that most mutations are tied to specific weather events or extremely rare map spawns, so knowing which ones exist and how to trigger them matters a lot.
Quick answer: The best mutation is Shiny at a 4x earning-rate multiplier. It spawns randomly on the map with a very low chance. For weather-based mutations, Bloodbound (2.5x) and Lovestruck (2.25x) offer the highest boosts you can actively work toward.

All Catch and Tame Mutations, Multipliers, and Obtainment Methods

| Skeletal | 1.1x earning rate | During Gravebound Weather, place a pet into the mutation machine. |
| Cupid | 1.2x earning rate | During Valentine's Weather, combine 5 identical pets to receive 1 pet with the Cupid mutation. |

Weather-Based Mutations vs. Map-Spawn Mutations
Mutations fall into two broad categories. Weather-based mutations — Seabound, Volcanic, Skeletal, Cupid, Charged, Admin, Cosmic, Frozen, Fractured, Lovestruck, and Bloodbound — require a specific weather event to be active. When the right weather rolls in, pets sitting in your Pen have a random chance of receiving the corresponding mutation. Some weather mutations also involve a manual step: Bloodbound needs you to gather Bloodmoon Grapes and feed them to a pet, while Lovestruck can be triggered by feeding Chocolate Hearts during Valentine's Weather.
Map-spawn mutations — Albino, Gold, Rainbow, Glass, Neon, and Shiny — work differently. Pets with these mutations appear directly in the open world, and you simply need to find and catch them. They tend to carry higher multipliers (1.75x through 4x), but their spawn rates are much lower, especially for Neon and Shiny.

How to Spot Mutated Pets on the Map
Mutated pets usually have a slightly altered appearance compared to their base versions. That visual difference is obvious for mutations like Gold or Neon, but far more subtle for Bloodbound, Fractured, and Cosmic. The most reliable way to identify a mutated pet is to look at the text directly beneath its name. A Gold-mutated crocodile, for example, will display the word "Gold" right under its species label. Keeping an eye on that name tag is especially important for high-value mutations like Shiny, where missing one catch could cost you a 4x earner.
Cupid Mutation and the Mutation Machine
The Cupid mutation is unique because it requires you to sacrifice duplicate pets. During Valentine's Weather, a Love Machine appears near your base. You feed five identical pets into it and, if the roll succeeds, one pet comes back with the Cupid mutation and a 1.2x earning boost. Using fewer than five pets (as few as three) is possible, but lowers your success rate. Failed attempts consume the pets permanently — they vanish from your inventory — so only commit duplicates you can afford to lose.

Mutation Diffuser — Toggle Visual Effects Without Losing Multipliers
If your Pen starts looking chaotic with overlapping mutation visuals, the Mutation Diffuser lets you turn off specific visual effects while keeping every multiplier intact. You can buy it from the Buildings section of the Lassos and Food Shop. Once placed, interact with it to selectively disable or enable the cosmetic layer of any mutation on your pets. This is purely visual — your earning rates stay exactly the same.
Traits vs. Mutations — They Are Not the Same
Catch and Tame also has a separate Trait system that uses the Trait Machine, a different building you purchase for $1,000,000 from the Buildings tab. Traits grant bonuses like a 1.2x Money Boost, 25% faster egg hatching, 25% breed luck, 20% mutation luck on hatched eggs, a higher chance of twin eggs, or the Rideable perk. Unlike mutations, traits require you to sacrifice at least three additional pets as fuel, and higher-rarity sacrifices (Mythical pets give a 1500% luck boost) dramatically improve your odds. A single pet can hold up to three traits.
The Mutation Luck trait is worth calling out specifically: it raises the chance that a hatched egg produces a mutated pet by 20%, making it a useful long-term investment if you breed frequently.
| Trait | Effect | Chance from Trait Machine |
|---|---|---|
| Money Boost | 1.2x earning rate | 28.8% |
| Hatch Speed | +25% egg hatch speed in Pen | 20.6% |
| Breed Luck | +25% breeding luck | 17.8% |
| Mutation Luck | +20% chance of hatching a mutated pet | 12.3% |
| Twin Eggs | High chance of two eggs after breeding | 10.9% |
| Rideable | Lets you ride the pet | 9.6% |
Re-running a pet through the Trait Machine replaces its existing trait, so plan carefully before overwriting a rare roll like Rideable.

Stacking multiple mutations on a single high-rarity pet and then layering a Money Boost trait on top is the most efficient way to maximize per-second earnings in Catch and Tame. Focus on keeping your Pen populated during every weather event, grab Chocolate Hearts and Bloodmoon Grapes whenever they appear, and always check the name tags of wild pets before passing them by — that unassuming animal might be carrying a Shiny mutation worth four times its base value.
