What to look for in food for a Cornish Rex

Named animal protein as the first ingredient (e.g. "chicken", "salmon"), not "meat derivatives" or "animal by-product".
Foods with adequate taurine. Be cautious with grain-free diets — the FDA has investigated a possible link with DCM.
A working / sport formula with higher protein (28%+) and fat (15%+) for sustained energy.

What to avoid

Untested boutique grain-free brands without taurine in the analysis.
Anything containing onion, garlic, raisins, xylitol or chocolate flavouring (common kitchen toxins for pets).
