Maybe, The Little Broomstick by Mary Stewart

Description from Novelist: A black cat that needs to rescue its brother from a witch's spell enlists the help of lonely ten-year-old Mary Smith.

Here is a review from Kirkus:
Scaled-down sorcery comes to Shropshire in the form of a purple flower called Fly-by-Night, a black cat named Tib and a diminutive broomstick which whisks little Mary Smith away to Endor College where the curriculum includes spells, invisibility and the grisly subject of "transformations." Mary has no intention of becoming an apprentice witch, but when Madam Mumblechook catnaps Tib for one of her experiments, she is forced to return to the college and out-spell the experts.

Do the authors Eleanor Estes or Barbara Sleigh sound familiar? They both wrote books with kids, witches, and cats.

Kate, is this a picture book (about 32-48 pages) or a chapter book with mostly words?

Does the cat alone go searching for the cat's (not witch's) brother?

[Kate]

I think it was a chapter book with a black cover and a picture inside a circle. It may have been an older book.
