As for your problem, i hope the following website will answer your questions:
http://www.spraying-and-marking.com/
"Another common form of territorial marking, urine spraying, is often stimulated by new visual or olfactory cues introduced into your cat's environment. If your cat can see or smell a visiting cat outside the house or is confronted with new furniture or a new pet or person in the household...this could be sufficient stimulus for your cat to "spray" in an attempt to define boundaries and confirm their social standing."
"Urination outside of the litter box should not be confused with spraying. Owners are dismayed to discover their normally well-behaved feline depositing urine in inappropriate locations. It is important to rule out a medical problem involving your cat's Lower Urinary Tract as a cause for the problem.
A trip to your veterinarian for an examination is recommended to rule out the possibility of infection or some other inflammatory condition involving your cat's urinary tract.
It is possible that your cat could be "marking" and breaking its litter training simultaneously, although they happen for different reasons. Check out the Feline Behavior site for more information."
