Living on the 15th floor, will rats climb up the drain of the toilet?

It is possible that rats are extremely vigorous and can adapt to various living environments.

No, according to the calculation of 4 meters on one floor, the distance of up to 60 meters, the mouse will not bother to do that.

Yes, I've seen it, rats are very powerful, and they can climb no matter how smooth they are.

Theoretically, it can, but in practice, it's very small, and it's not going to happen.

No, don't worry, rats generally have a fear of heights.

Haven't seen it should be unlikely.

I don't know how the rats did it, but the 28th floor came up and hid in the ceiling of the kitchen.

No, the plastic pipes currently used are very slippery, the toilet walls are also very slippery, and there is no telling which floor will flush at any time, and there is only a dead end for rats to climb in.
