Hi,
My mother is on oxygen which is supplied from an oxygen concentrator
to the cannular (nasal tube) by a clear plastic tube (like aquarium
tubing).

Her cat loves to chew this tubing resulting in lost oxygen pressure
and several medical crises.  The cat has been squirted, yelled at
when caught at it.  We
have tried painting the tubing with bitter liquid,hot sauce, soap and
other deterents,  to no avail.  We have to repair the tube with
electrical tape, but we  cannot wrap the whole tube in tape.  At
night, we suspend the tubing
from hooks out of the the cats reach, but during the day, as my
mother
moves around, the cat starts chewing. Its quite a long tube so we
can't alway see when the cat is at it.

Help. My mother loves the cat, but its looking like the cat might
have
to go.

How can we stop the cat chewing the tubing?

Thanks
