I wanted to say giant squirrels but you couldn't control it. It would just climb up trees and run across the road when a fast moving cart approaches.

So... are senche-tigers khajiit? I'm confused.

(from UESP)The following details that information specific to each separate "breed" of Khajiit.
<snip: irrelevant to question breeds>
Senche:
The Senche is commonly employed by the other Khajiit breeds as a steed, presumably by will. Roughly the same height as the average Altmer, with an average weight comparable to that of twenty Altmer.

Senche-raht:
Larger and slower than the Senche, the Senche-raht are also possessed of a shorter body-span and straighter legs. The average Senche-raht stands as tall as two Altmer and can weigh as much or more than fifty. Like the Senche, Senche-raht are also employed as steeds, notably in battle, whence they earned the title "battlecats" from Imperial troopers.

(from UESP)Khajiit are each subtly bound to the Lunar Lattice, a mysterious force entitled the ja'Kha'jay in their native tongue. The Lunar Lattice determines the form a Khajiit assumes in life, according to the phases of Masser and Secunda at the time of their birth; while Khajiiti newborns appear incredibly similar to one another at birth, their future form becomes clear in a matter of weeks. This is due in part to the fact that, although born smaller than the children of either man or mer, the Khajiiti mature at a significantly faster rate.

It is imperative to note that while the Khajiit derive their natural form from the moons of Nirn, their peculiar tie to such is in no way related to lycanthropy, for, unlike that disease, it is neither contagious nor temporal. A Khajiit will retain its form of birth throughout their life and the moons, although they affect in what form the Khajiit will be born, do not affect it after that. Furthermore, there are no known shapeshifting Khajiit.

There are rumored to be "more than twenty" forms of Khajiit.
