I’ve seen toms do this.
They can let out an amazingly huge stream up in the air behind them.
(You’d think this act meant squatting and letting out a stream like they do when they urinate)
we have an almost 5 month old male kitten....I couldn’t believe the “stream” he let loose in his cat box last night as I put him in his room for the night....he’s getting, ahem, cut in about 3 weeks...and NO, he does not, and will never, go outside (if we can help it.)
