A black cat is the easiest Halloween subject to draw and the easiest one to ruin, and both happen for the same reason.
Somebody in a comment last October told me her cat looked like a black blob. She sent it over. It was a genuinely good cat drawing.
Correct proportions, careful whiskers, fur texture on the chest, little claws. Then she had filled the whole thing in black and every one of those decisions had vanished.
That is the trap. A black cat is not a cat you colour in at the end. It is a silhouette, and a silhouette is read entirely by its outline and by the few shapes you leave white. Everything you draw inside it is going to disappear, so the work has to happen somewhere else.
Once you accept that, learning how to draw a black cat gets much easier and much faster.

How to Draw a Black Cat Step by Step
Step 1: A circle and an oval
Draw a circle near the top of the page for the head. Under it and slightly to the right, draw an oval about twice the width of the circle for the body, sitting on an invisible line.
Keep them light. Everything from here builds on top and nothing gets moved.
Step 2: Ears and tail
Two triangles on the head, set apart rather than close together. Wide-set ears read as cat from a long way off. Close-set ears read as fox.
Then the tail: one curve rising from the right side of the body, higher than the head. A tail that stays low disappears into the body once everything goes black.
Step 3: Legs and haunch
Two front legs dropping straight from the front of the body, and one curved haunch at the back. The haunch is the rounded shape over the back leg and it is what stops a sitting cat looking like a bottle.
Keep the gap between the front legs open. It will matter in a moment.
Step 4: Join it into one outline
This is the step that decides whether the drawing works.
Go around the whole cat and connect everything into a single continuous outline. Lose the construction lines where shapes overlap. You want one closed shape, not a circle sitting on an oval with legs attached.
While you are there, exaggerate. Make the ears a little sharper, the back a little more arched, the tail a little more curled. A silhouette has no interior detail to carry it, so the outline has to do all the work and a timid outline reads as nothing at all.
