Minecraft Preparation:

1.Dig a 2x2x2 hole, and put in 2 adult ocelots, and 2 baby ocelots.
2.Give yourself a stack of fish
3.Enter survival mode
4.Start feeding the ocelots fish.

What I expect to happen:
Whenever I feed the ocelots: If they can activate love mode, they consume a fish (had 64 fish, now have 63), and they will enter love mode.

Otherwise, nothing happens.

What happens:
Whenever I feed the ocelots: If they can activate love mode they
consume a fish.

Otherwise, they will still consume the fish, BUT: if you were feeding adults, and now go on to feed a baby (the possibility of which is also kinda..) you will get back all the fish you fed to the adult one previously.
If you were feeding babies, and go on to feed an adult, the same applies. Even if at some point you have 0 fish, you will get them back, as long as you don't trigger love mode.
