I don't think so but maybe
Hamsters need baths atleast once a week or up to two times a week
about 1 week.
3 times a week
A planarian can live without food for about a week.
Cockroach

About a week.
No hamsters arent messy pets but you have to clean their cage once a week cuz it stinks
about 1 week
Well,some hamsters could but not all of them. I have a 2 hamsters a boy and a girl then a week ago they had babies I think they had 11 of them bu one of them died the mom killed it because she had to many.Now they are a week old they are so cute but you do not want to disturb them in this period of time.
about 1 week without food
You should absolutely leave baby hamsters alone until they are weaned.
