The cat exchanges places with a drawing of the cat60;506c DикаVv 2 aSs h
Given
CAT RENDERING
see if you can get them to exchange places, resulting in
RENDERING CAT
by transferring one "chunk" of letters at a time.
A "chunk" is a consecutive string of letters taken from anywhere within the word. It can also be inserted anywhere into the other word. It must consist of at least two letters (no single-letter chunks), but there is no length limit. The transferred chunk does not need to be a valid word.
Demonstration of the movement:

While this example happens to show the movement of the transfers alternating between right to left and left to right, this is not a requirement. At each step, you may transfer the chunk in either direction as you choose.

1$\\begingroup$ @Duck — I feel that in its structure, it is a river-crossing problem. You have to get something from one side to the other (or, in this case, two things to opposite sides simultaneously) under certain constraints. $\\endgroup$ – SlowMagic 15 hours ago

$\\begingroup$ Yeah, I didn't read tag description. Started on the puzzle! $\\endgroup$ – Duck 15 hours ago

$\\begingroup$ Can you have one of them as two words, for example, one of them is black cup and the other is cube? $\\endgroup$ – Duck 14 hours ago

$\\begingroup$ Since it's not required to zig-zag all the way, you can skip the third line (from both ends) altogether. $\\endgroup$ – Bass 7 hours ago

$\\begingroup$ @Bass Skipping the third line would mean a step with a single letter and it's stated in the OP that a chunk needs to be at least two. $\\endgroup$ – John Clifford 5 hours ago
