I just read your post about groceries in the city. I've got a couple of comments. 1) You can grow some stuff in pots. There's a lot of information about container gardening, check your local library. Also, many citys have community gardens, yours might, ask! 2)My cheaper alternative to cat litter is oil dry, you buy it in 50 lb bags at an auto parts store. If I could find simply clay around here (semi rural) I would buy that, but I can't. Anyway, it's about $10 per 50 lb bag, much cheaper than store-bought cat litter!
I really liked your post, I hope you write more!
