My cat is normally very well behaved - he is used to going outside and always uses his litter box.
However he has recently had surgery on his foot and must stay indoors and wear a cone on his head for another 10 days. This is understandably stressing him out and making him very unhappy! This has resulted in him spraying and urinating around the house, especially in the mornings and evenings when there is a lot of activity in the house with people leaving/arriving home and opening the doors - which is the time he is normally allowed in or out of the back door. During the day time he has been much more relaxed and sleeps, and does not urinate.
I am keeping his litter box fresh and clean, with easy access to it and praising him when he uses it. I have also bought some Feliway hormone spray which I am using, and making sure to thoroughly clean where he has peed.
Is there anything else I can do to stop him urinating indoors, or alleviate his stress (which I think is causing his urination) until he can go outdoors again?
