I have two fabulous male 6 month old brothers who were just neutered YESTERDAY. The surgery went SO well - they acted as if nothing happened at all. They have NEVER had a problem with using their litter boxl, until today. I got home from work, and they were acting perfectly normal. Neufi pooped in his box, then jumped up on his favorite lounging chair (a little cube bean bag) and peed there. I couldn't believe it. Does anyone have a clue why he would do this out of the blue and how to do my BEST to ensure that it won't happen again? It soaked all the way through to the very bottom - I'm not even sure I can wash out the beans, so I might have to throw it out. But will he do this in other places? I'm so surprised, I don't get it at all. I didn't change any of their environment recently - the only big change is the surgery, but again, they acted so normal afterward. Peftectly healthy, happy, energetic as always. Any thoughts???
