Hi Carl,
I am happy to report to you that what your cat is doing is normal as Kate mentioned "most cats have their individual habits" some that we humans do not understand.
I have a number of cats in my home that all came from rescued situations so I have seen and encountered alot of what I thought to be strange cat behavior but I have learned that they are animals with their own ways of doing things.
I have 3 cats that do the same as your cat.
Everytime I come home or get out of bed in the morning they all 3 RUN to my feet and almost nudge me toward the bathroom. (chattering and mewing the whole time).
Once I'm in there , they rub against my leg and purr like a little motor running.
If I am in the kitchen cooking and leave the kitchen to go into another room it dont matter where those 3 are or if they are even in a deep sleep...they all 3 jump up and head for my feet and begin to push me toward their favorite destination.
I have one thought as to why this might be happening. Excuse my blunt speaking here but I think that when we go to the "potty" It allows us to be kind of alone with the cats that like to have us all to them selfs.
(cats ARE very jealous animals)
Maybe being it is a smaller , more closed in room that they feel safe to ask for our attention there and to maybe not have to share us and our attention with another house cat.
This is just MY thoughts on it but I am certain your cat is just being its self and not displaying any behavior that you need to be concerned with.
Enjoy your cats attention as what your cat is doing is displaying its affection and desire to be closer to you even if for a moment.
Best wishes to you and your beautiful kitties.
