Fat Cat is a Rare pet from the Muffin Bake update in Grow a Garden 2. Its reported route is the Sugar Egg pool, and its main effect is simple: while equipped, it makes your avatar larger. The route is not confirmed as active now, so check the live egg and event listings before you start hunting.
Fat Cat is a Rare Sugar Egg pet
Fat Cat is described as a ginger cat with white eyes and a large body. It is tied to Sugar Egg rather than the normal lobby pet-spawn route, so searching the usual pet area will not help much.
The listed Fat Cat chance is 19.97% in the Sugar Egg pool. That is roughly one in five reported pulls, not a guaranteed result from every egg.
How Fat Cat enters the pet pool
The reported acquisition path is to hatch a Sugar Egg. Fat Cat is one entry in that egg's listed pool, so the 19.97% figure describes the chance assigned to Fat Cat when the egg rolls through its pet options.
Sugar Egg availability needs a live check. It is currently marked as no longer obtainable, but that status may change if the event or egg returns. Check the in-game event and egg listings before assuming you can hatch one.
What Fat Cat does when equipped
The normal Fat Cat effect is reported as ×1.15 player/avatar size. This changes your character's displayed size. It does not raise crop value, improve seeds, increase selling returns, help with stealing, or add defense. A larger avatar is still just a larger avatar, which is a very specific sort of flex.
Some variant figures are still uncertain. Big is listed at ×1.3, Mega at ×1.5, and a Mega Rainbow example at ×1.625. Rainbow versions are described as scaling beyond the base value, but the variant labels and numbers need live in-game confirmation. Treat these as reported reference values, not a confirmed official stat table.
Should you chase Fat Cat?
Fat Cat makes sense if you want the oversized look or collect unusual pets. It is a cosmetic-size pick, not a farming specialist. If your goal is crop growth, mutation, stealing, or defense, compare the farming-focused choices in the best pets to get first in Grow a Garden 2 and the wider Grow a Garden 2 pets tier list.
For the broader egg pool and Sugar Egg entry, use the Grow a Garden 2 egg collection. Check the live game before spending resources because Fat Cat's reported route may be tied to an egg that is no longer active.
