Royal Canin Indoor Adult, 15# bags, 3 per month (~$125)
Friskies canned, 8 cans per day (~$110)
Royal Canin SO, 5# bag lasts about 2 months & is for Taranis only (~$15)
Can't afford treats for obvious reason.
Litter is wood stove pellets at about $6 per bag, use 1 per week.
Newspaper for the disabled cats I get free from the library when they are discarded.

Since I have 8 foster cats, I often get the pellet litter from the shelter which saves me a bit, and if I'm really hurting some months I'll get a bag of Hills dry from them to mix in with the Royal Canin.

I haven't bought toys for at least a year because I can't afford them but the old ones are fine and they love things like crumpled paper balls, avocado stones, grocery paper bags, pens, large hair clips, and each other.

I get part of a sofa bed and they get most of the bed, two sofas, one love seat, one day bed, a number of soft armchairs and padded side chairs, floor cushions, a couple of low chests padded with comforters, two desks, two tables, and the lower shelves of several bookcases and shelf units. And now that I write this I'm wondering how much of my home is mine!
