There are a few theories of invisibility and they depend on the mechanism of invisibility
The first type of invisibility is all cells are transparent, sort of like a jellyfish. In this case the digestive system would be visible if you’d eaten food. Not ideal, visible poop.
Second is light bending, like the predator. In this case poop would be visible and you wouldn’t be.
Third is magic true invisibility, and in that case it depends on the wizard.
Fourth is illusionary where the viewer is tricked into not seeing you, and in this case the poop is visible.
Would the poop retain the invisibility after exiting your tiger body?

It’s clear you’ve given this a lot of thought 😁
They’re the less ideal wizard
