Here are some examples:
* Пушистый котенок (poosh-is-ty kote-nok) - Fluffy kitten
* Пушистая подушка (poosh-is-ta-ya pa-doosh-ka) - Fluffy pillow
* Пушистое облако (poosh-is-toe ob-la-ko) - Fluffy cloud
It's worth noting that while "пушистый" is the most general term, there are other ways to express "fluffy" depending on the context:
* Пухлый (pukh-ly) - Used for things that are soft and round, like a fluffy cheek.
* Мягкий (myag-kiy) - Means "soft" and can be used for things that are fluffy, but not necessarily "furry."
The best choice will depend on the specific thing you are describing.
