Aggressive behavior towards newly neutered cat.
I have two male cats, one two years old and the other 9 months old. The two of them have bene completely in love with one another since the day we brought the kitten home in October. However, a few days ago they had a spat over a girl cat at the window. It was scary, but they relaxed over the next day and fell back into a routine. Worried about the spat, I decided to get the kitten fixed. He had surgery today. Since brining him home, the older cat has totally rejected him, meowing and hissing at him if he gets close. The older cat seems edgy and not relaxed, watching the younger kitten. I am worried and don't know what to think of this behavior. I have loved watching them play together, sleep together, and take care of each other and am confused about what has changed. Help!!

don't worry this is a common problem especially after one cat has visited the vets.
Basically your kitten will smell strange after his visit and this has scared the other cat.
the best thing to do is to give them a day together using the introduction method described on this page
It allows them to relax with each other again without the fear of attack etc.
they should settle down again with each other soon.
