So sorry hear you lost your cat! Can I recommend catmint (botanical name Nepeta). Grows as a small shrub, dies down in winter and comes again in spring. As the name implies, cats love it, rubbing their noses in it makes them go all gooey! No problem to dig up and replant so long as you take a good rootball with you.
PS: You should be able to get it in any good garden centre or nursery.
