Classic sounds missing that weren't missing in Vanilla

Okay - I bought the fact that Kodo mounts didn’t have walking/running sounds while mounted since I rerolled horde a few months into Vanilla, but I’m not buying that vanity pets didn’t have any sounds when clicked. I remember getting a cat and making it meow all the time. Mech chicken, all the other great sound effects for vanity pets - not in WoW Classic.

What’s up w/the missing sounds? I hear warlock pets and some hunter pets are also missing sounds that were supposedly added in patches very early on but not in Classic still. I know it sounds trivial, but it added flavor and detail I miss in Classic.

I got this issue too with my 60% mount and the sharptooth frenzies in ZG and in STV.

It could be an addon error thing idk

Disabling all addons was the first thing I tried. I’ve had other people tell me Kodo mounts don’t have footfall sound at 60%, but nobody can confirm the vanity pets not having sound is universal or just me.
