a black fur with a short tail

a is wrong. It has black fur. Fur is uncountable when describing the hair of an animal. It is countable if someone has some piec of clothing made of fur, e.g. "That is a nice fur."

b is correct.

Thanks. Can I say,

It is a black fur Persian.

Gordon, would it be better to say "It has black coat"?

.

Old Man GordonIt has black fur.

Sometimes, I wonder if there's any difference between coat and fur.
Thanks in advance

so, are these sentences correct?

(a) It is a black fur Persian.
(b) Is it a black fur cat?
(c) Is it a black fur Persian cat?
(d) Is it a black 1-year-old Persian

Are these sentences correct?

(a) It is a black fur Persian. - It is a Persian with black fur/a black coat.
(b) Is it a black fur cat? - Is it a cat with black fur? or simply - is it a black cat?
(c) Is it a black fur Persian cat? - Is it a black Persian cat?
(d) Is it a black 1-year-old Persian

Thank you very much!!

I have had cats for 15 years, and have never used coat to describe their fur. More often, I just say 'She's brown." But the word coat does have the same meaning. I think it is used more by professionals working with animals.
