Unfortunately, you can't have both cats and plants at the same time.

I also got a Serano Hot Pepper plant https://bonnieplants.com/product/serrano-hot-pepper/.
All three starter plants were about $4 at my local big box store.
Apart from these, I planted some green bean seeds and one of them has sprouted.
Last year, I bought a dwarf Meyer lemon tree which has lived up to its promise of growing well in a container and providing abundant fruit year-round.
I also bought solar-powered garden decor. These stakes look pretty during the day but at night they are absolutely magical. https://www.target.com/p/gerson-international-43-inch-high-s...
Ladybirds (you can buy larvae which you can release in about 10 days) also works for aphids, they gobble them up.
So we decided to buy one plant per month instead. Plants are great, they look nice, can turn any boring room into a cozy space, and there is also a lot of geek factor when researching plants, maintaining proper watering and feeding routines but unlike fish tank, plants can survive when you are on vacation or accidentally over-water.
