I get that humans can't understand the talking animals, but do they not notice that they wear clothes?
They probably do, but in this universe there doesn't seem to be anything unusual about animals wearing clothes. The humans would just think of it as normal; maybe they'd notice it more if they saw an animal that didn't wear clothes. "Hey, look at that mouse, Bill, not a stitch of clothing on him! Times must be hard."
I suspect this is just one of those little quirks with Civilized Animal fantasy stories that you're just not really supposed to think about too hard.
Why is Tanya so arrogant in the last two films? In the first ones she was more close and lovely to Fievel.
She's growing older and entering the age where she begins thinking of herself as "grown-up" and "done with childish things." And so the younger Fievel, who is still playing around, comes across much more as an Annoying Younger Sibling in her eyes, hence she has less patience with him. It's not an uncommon phase for older siblings to go through.
An American Tail
Where did they get the idea that there were no cats in America in the first place?
Same way the human immigrants got their unfortunately false misconceptions about America.
Yup. "The streets are paved with cheese" was a reference to an actual belief that America was so ridiculously rich that they paved the streets with gold.
Why did all the other sweatshop workers never think of tying their sheets together into a rope and going out the window before? Why did they need a little kid to tell them they could do that, when at least one of them is clearly an adult? And what made them think Fievel was crazy and it wouldn't work?
How high they were up was probably a discouragement, and Fievel's idea was crazy. Crazy enough to work.
More likely, they just didn't see the point. To even be "working" in the sweatshop they must have no family, no money, no place to go. Why run away and risk ending up on the streets starving, when they could stay where there's guaranteed food and shelter?
We can assume that after they escape from the sweatshop, they notify the authorities of it and they arrest the owner. What he was doing was basically keeping them there and using them as slaves.
When the cats capture Fievel, why do they put him in a cage instead of just killing him?
Maybe they were planning on sending him back to the sweat shop?
Warren could have been planning to use Fievel as some kind of bargaining chip, perhaps.
They weren't hungry at the time and were saving him for later.
So is there any particular reason why a bunch of cats were travelling across the frozen wastelands of Russia with the Cossacks? I know the point of this is that it would run parallel to the prejudices that the Jews faced, but how often do soldiers bring cats to a warzone? Dogs? That I can understand. But cats?
I was always under the impression that the cats weren't with the Cossacks so much as scavenging off them.
Another possibility is they were brought along as provision guards. Mice, small animals, etc could get infi supplies, which could lead to shortages. Bring cats, and suddenly those small animals aren't a problem...
What was the deal with the evil-looking Poseidon-shaped wave during the storm at the very beginning? I guess one might argue that it was Fievel's imagination, but the scene was clearly not from his point-of-view. It just seemed really out-of-place.
Why are the cats in the beginning so unrealistically terrifying and why do they roar like lions? Is that what they sound like to the mice?
I'd assume that's the reason. This is all from the mice's point of view.
The Treasure of Manhattan Island
In The Treasure of Manhattan Island how in the heck are the Native Americans growing crops in an underground cave where there's no sunlight? Where do they get the huge fruits and vegetables we see them feeding Tiger?
