i made a blanket hidey

I would say if they do not even come out to eat or drink, then you should probably take it down. However, if they are moving around a bit and still doing their normal duties, then it should be fine. But since they are less active, you should schedule floor time with toys and such (without the blanket hidey) so they can get in some exercise.

i am just saying that they are less active now.
I will do that

they move around alot more with a piggie forest
