I have 2 cats. Both are fixed. One is 12 years old and one is 6. Both
are indoor cats only. They have always gotten along and been very good
friends. A few months ago the older cat, Willie, was up on the window
ledge when a stray jumped onto the ledge outside. This stray was in
heat and she sprayed Willie through the open window and screen.
Needless to say the other cat, Cujo, went insane. She hissed and
growled and screeched. She even attacked him once. But a few days later
when the scent faded she returned to normal. But ever since then, every
once in awhile she will look at Willie and screech and hiss and growl.
She looks like she doesn't have a clue who he is and she looks like she
wants to kill him. Some days it only lasts 5 minutes but other days it
lasts for hours. Has anyone experienced anything like this before? Does
anyone have any advice or ideas as to what I can do? Any help is sooo
appreciated. Thanks.

Nikki
