Spot first shows up in Data's Day with seemingly no canonical explanation to how he got there.

Then not to mention that they switch to a completely different cat in later episodes.

In previous episodes they were not near earth to go pick up a cat. Unless cats exist on other planets of course.

I know its kinda dumb, but I brainstormed the idea of Data creating Spot using Soong type technology.

EDIT: For all of yall that say Data replicated Spot, this is not possible. Replicators can not create living beings. You are missing the quantum signature. Even a medical replicator is not capable of this. Pretty much what you would be able to make is a cat body with no life or soul in it.
