Nickel. It provides both corrosion resistance and increased ductility which makes the material more likely to bend before breaking. I like using it to weld onto busted taps to try to back them out because the weld will flex a little bit instead of just snapping off.
A tip i learned with my most recent cat is getting the food and water up off the floor. Helps them swallow better. And the flatter the plate you give them their food on, the better. Cats can be extremely fussy over anything touching their whiskers, so anything you can do to help them with that they’ll appreciate.
