I read somewhere that said only poo and toilet paper should go down the toilet. However I don't think this is true enough, for example the following is often believed to be ok:
1. Puke
2. Dead fish
3. Hair (pubic or head)
4. Nails
5. Facial tissues
6. Dead insects, cockroach, etc.
Some of these are also sometimes flushed down, however less ok:
1. Bandaids
2. Teeth floss
3. Cotton buds
Also are kleenex flushable toilet wipes can be flushed now?
Wtf…
