Try succulents, or cacti if you are willing to deal with the spikes and pain of replanting them. They are easy and drought tolerant! Herbs are good too, but are a bit finicky, and plants that grow from clippings are good as well. I have a few tropical plants ( I live in TX). None of the plants I have are cat or bug resistant or repelling though, for the cats maybe just try to get them to lose interest? Place them on a windowsill and check them ~every 3 days or week or so, depending on if you remember. Good luck!
