He's 7 and I've had him since he was a baby,
he's always made this sound (has a soft rumble similar to that of purring, also kinda sounds like he is softly whining and breathing out air) and I have NEVER been able to figure out what it means.

He does it all the time. Especially when I pet him. I'm not sure if he likes my petting or not, maybe he just uniquely does not like to be pet? (I pet him softly of course)
I've tried recording it on video so I can more accurately ask my question but the sound doesn't pick up very well.


Does anyone have any experience with anything like this?
reeeallly?? you guys think he likes my petting??? . I was always afraid I was bothering him by petting him
