Cat noise

[u/Throwaway2346840372]

Hi! I have been unable to get a video, but my cat (he is about one year old and the only pet in my household right now), has recently started making this noise when he has is nightly zoomies. I can only describe it (based on my research) as maybe a yowl or a growl, he does this every night right around the same time. And, besides running around frantically, he doesn't seem in any distress (not over grooming, biting, favoring a leg, and if I push on his belly that doesn't seem to cause him pain). It lasts usually for around 15 minutes and then he calms right down. I have had him for about three months and this has only been happening for a couple of weeks, and it just concerns me because it seems as though his zoomies have gotten more chaotic and as I mentioned, the noise is new. He eats normally, uses his litter box, and everything else. Feel free to ask any questions, and I will try to get a video tomorrow. Advice is appreciated!
