So this is what Miaowara Tomokato's armor would look like.
I don't think I could shoehorn Milo into that getup though. Most of the suits don't let the cat use his main weapon: his mouth. They also keep them from using their ears properly. On the other hand, given how much Milo loves wearing clothes, not being able to use his mouth isn't much of a disadvantage.
The samurai armor isn't the only one on that site. If you want to create some warped feudal version of Tom & Jerry, there are mouse armors as well.
