Sorry to hear about your cat situation :\
I was originally going to suggest laminate, but that requires more tools and time, so unless you come equipped with a circular saw, then I have a different suggestion.
Vinyl Plank: Very easy installation, no glue underneath needed, and minimal cutting. They actually glue to each other and go down really nicely. All you'd need to keep handy is a razor blade and a straight edge to make nice, even cuts.
I would however let the flooring acclimate for 48-72 before you install it, despite it not being real wood.
