Why does "та ночь" become "ту ночью", in "I saw a cat, that night"?

"Ту ночью" is ungrammatical. It should be either той ночью or в ту ночь. And no comma is needed. And it's more natural to put it before я видел кошку. Or, more colloquially, between я and видел.

Why does "животное" become "животные" when "animal" becomes "animals"?

The ending changes similar to those of adjectives (зелёное, зелёные и т.п.) since this word was originally an adjective. You can think of it as short form of "животное существо" (animal creature).
