I wonder if someone can help us. My wife and I have two Siamese. Lily who is 15 and Harley who is 4. Absolutely no problems until a year ago when we introduced Sonny - now 2 years old. All have been spayed.
Unfortunately he regularly appears to be "marking his territory" on bedding in the cat basket and sometimes our washing when we are getting it ready to put into the washing machine. We have tried different deterents that people have advised (orange peel, calming sprays) - but nothing appears to be working?
All three use the two cat trays in the kitchen ok.
They are house cats who only go out into our back garden when we are in attendance.
