Item drops from iron golems and cats aren't affected by the looting enchantment

Item drops from iron golems and cats aren't affected by looting enchantment. Here's the list of mob drops without looting enchantment

• Iron Golem drops 3-5 iron ingot and 0-2 poppies
• Cat drops 0-2 string

Steps to Reproduce:

1. Make sure to enchant your sword with Looting 3, using /enchant @s looting 3
2. Summon Iron golem and cats
3. Kill it using the sword enchanted with looting and observe the loot that it drops upon death

Observed Results:

• Killing Cat doesn't increase string drops
• Killing Iron Golem doesn't increase Iron Ingot and Poppy drops

Expected Results:

Both cat and iron golem drops would be affected by the looting enchantment.
