The bug
Tamed ocelots (cats) sneak to a player holding fish just like they do when they are not tamed.

It might be "Works as Intended". At least there is a report then and people don't have to create a new one.
Can confirm for MC 1.12.1.

Confirmed for 1.13.1.

Confirmed for 19w41a
Can confirm in 21w03a.

@@unknown, this report was originally about ocelots when cats did not exist as separate entity yet.
However, in 21w03a I am unable to reproduce this for cats. Are you able to reproduce this for tamed cats?
If this still occurs for "trusting" ocelots, can you please create a separate report for that (I am able to reproduce it for them).
Why can't they do that? They still might want to eat fish even tho they are tamed.
