Similarly, for mucking out the bottom of the rat cage (or other small animal cage). Just remember to count the rats before disposing of the plastic bag… or was it only my Skinner who liked to go exploring in the dirty litter bag?
We use cloth bags as much as possible and the plastic supermarket bags still overflow their container from time to time. I don’t understand.
Since the popularity of reusable bags, I don’t get a lot of them, but use up the ones that I do get. Some uses:
Studio trash bag - I hang one by both handles from my main desk in the studio for arts and crafts trash.
Conditioner cap - When I deep condition my hair, I use one of these on my head to keep clothes and furniture from getting messy. You can tie the handles to keep it on. Works well for dying your hair too.
Butt bag - I smoke outside and use a bucket with cat litter for butts. I scoop every couple of days and use a bag to keep them in outside (so they don’t smell up my home) until trash day.
Refrigerated garbage - During the summer months, vegetable peelings and the like go into one of these in the fridge so as not to draw flies to the outside trash can. On trash day, they go in and are magically carried away while I’m sleeping. 
We keep a few at home to use for emptying the cat litter tray, and also for emptying the dust and fur out of the Dyson when I’ve vacuumed the carpets.
Yeah, I used to use them for that when I had ferrets. These days they make nice litter box liners for the rabbits, and for cleaning out their cage.
knit a plastic bag from them. that uses up about 10-20 of them.
Dragster parachutes… as long as you have a really crappy dragster.
I like that knitted plastic bag from plastic bags! It would make a good plastic bag holder, to save bags up to return to the recycle bin at the grocery store. (I made a holder by sewing two placemats together, with a string handle, to hang from a doorknob.) I stuff excess plastic bags into this, and also other plastic bags - I was told if you can stick your fingers through any plastic, it can also be recycled.
Got a pet who’s a puker? cover up the barf with a paper towel or sheet of newspaper and let sit a few minutes to ‘solidify’ some. Put plastic grocery bag over your hand, scoop up, and dispose. Easy peasy.
We used to go through several a day for dirty diapers. Now I use them to take my lunch to work.
On kayak trips we put a few into each boat. Storing wet clothes, keeping track of empties, and collecting found trash are a few uses.
Dog poop. Liners and bags for the small garbage containers (we have four little waste baskets in the bathrooms, bedroom, etc.) Car garbage bag. (I loop one handle over the gear shift, the bag hangs in the passenger foot well. Convenient to use whilst driving.) Two are ready to go with me to work today with my running shoes in one and my workout clothes in another. My lunch will go into a third. (I must use my Laptop Lunch container more.) Small waste basket outside the house where full dog poop bags and cigarette butts go (so they don’t come into the house.) Organise stuff I don’t use a lot–e.g. hosiery in the summer, bagged and waiting in the bureau drawer until autumn. A bunch in the trunk of my car for impromptu purchases at markets (farmers’ markets and such) and also to reuse for shopping (a lot of stores are not automatically giving you a bag). Library books to go back. In the luggage to separate out dirty clothes from clean and wrap toiletries.
I never throw them away–they have to lead several lives before ending up as garbage.
Something about the wording of that post made me laugh a little.
I’m hoping there aren’t dirty diapers in the bags anymore.
they knit up really easily!
i use old tissue boxes to store the bags. the “pop up” small square not the large “lay flat” tissue boxes. double recycling!
there was a store in my 'hood that would take in shopping bags instead of buying them. they really enjoyed the pop up bag boxes, really easy to get one at a time.
Now that is brilliant! Makes me wish I had thought of it or at least lived in a place where I could take advantage of subway grates and make some of my own.
I use them for cleaning my cat boxes. If they ever make them illegal around here (which they’re talking about trying to do), I’m going to have to stock up before they do.
We use them for collecting dog poo too.
Your library may take donations for people who check out a bunch of books and want something in which to carry them home.
A toy for kids to play with
I don’t have kids, but I refuse to believe that they are stupid enough to die from plastic bags when the actual hole for a plastic bag is like 50% of the whole bag.
My workshop is about 300 feet away from the house, and when it rains hard, most of that distance is either running water, standing water, or mud. If you walk through there, you will have water come over your shoe, soaking them, and the treads will fill with mud.
I take a couple of the larger grocery store bags (bigger than the ones for a gallon of milk) and pull them up over my shoes and tie the straps together across around one side. With my “ghetto waders”, I can walk to my shop with my shoes only getting slightly wet on the bottoms - no soaked socks and no clogging with mud.
I usually use my own shopping bags but intentionally forget them every so often to get plastic bags. I use them to carry the recyclables downstairs to the bin.
We use ours to line the bathroom trash cans, and for picking up dog poop in the backyard. When we walk the dog the bag the NY Times comes in is the best.
