Achievment Glitch

Hi Mojang Development team!

I was playing on the latest java edition snapshot when I encountered a bug
first I fed a baby horse a golden apple to skip to adulthood (not sure if that's the cause or not) but
when I tamed it I got the "friends forever" achievement as usual but I also got the achievement for taming all types of cats when I had not spawned in , tamed or even saw a cat

this dose not majorly effect the game but is still a bug that I think could be fixed easily
thank you for your time

yours truly kieran
