My mother loks after a neighbours cat very ofyen during the day.
Frankly, the neighbour is quite neglectful of the cat hence my mother's
intervention. The cat isnt tray trained and it appears to be between one to
two years old  It does wait by the door to be let out when it wants to "go".
My mother has her own cat which is fully house trained. Is there anything
that could be done to train the neighbours cat?
