Edit: Upon further testing in a singleplayer, local, world the behaviour is unchanged. Once laying in a bed, the cat will purr consistently, and can still meow whilst purring. This was verified by teleporting to 2 random villages and replicating an equivalent situation. Once arrived, I removed most of the villagers in the area, along with every cat in loaded chunks, before spawning a single cat, taming it, and waiting inside of a villager house. I have recorded more footage, which has been added to the media section of the article.

I have been playing on a server powered by ShockByte lately, and I just recently obtained my first cats of the world (3 of them). I have noticed some strange behaviour. For some reason, upon lying down on a bed, my cats will purr consistently, with no stops for minutes on end. I recorded a 3 minute clip, of which 5 seconds have been attached to this report, and before and especially after which the cats continued to purr. At a few points there were several cats lying down, so that could introduce some overlaid sounds, making things seem consistent when they are not. That being said, for more than 2 and a half minutes, a single, lone cat continued to purr consistently, with no breaks or pauses. I am unsure if this behaviour is intended or unintended, as I have been scouring the wiki, and I cannot seem to find the duration that cats should be purring once laying on a bed, only that they do so "Randomly" (citation: https://minecraft.wiki/w/Cat section "Sounds"). The main reason I find this behaviour strange is I don't seem to remember dealing with this in the past.
