Breeds known for fluffy fur and bright blue eyes:
* Siamese: Siamese are known for their striking blue eyes and short, fine coat. However, they usually have a pointed pattern (darker coloring on the face, ears, legs, and tail). Your cat might be a Siamese mix.
* Balinese: A long-haired version of the Siamese, with a similar pointed pattern and blue eyes.
* Ragdoll: Ragdolls have long, semi-long, or short fur, and often have blue eyes. They are known for their calm, docile nature.
Breeds known for grey spots:
* Russian Blue: Russian Blues have a short, dense, blue-grey coat and green eyes, but they do sometimes have a silver tabby pattern with grey markings.
* British Shorthair: British Shorthairs have a dense, short coat that can be various colors, including grey. They have a round face and a stocky build.
* Chartreux: This breed has a dense, short blue-grey coat and copper-colored eyes. Some individuals have a silver tabby pattern.
Other possibilities:
* Domestic Shorthair: This breed is a mixed breed, so it's possible your cat is a Domestic Shorthair with genes from different breeds that give it its unique features.
Remember: Many cats are mixed breeds, making it impossible to say for sure without a picture!
