Usually Basil and Lapka get along very well.
And usually sleep together during the day and night.
She growls at him once in a while when he wants to play and shes not in the mood but lately shes been really different after this:
There's a stray kitty that's been roaming outside, one day the cat showed up at my screen while Basil and Lapka were both in the Lanai.
Lapka started screaming like a bat out of hell, and so I brought them both inside, but then she turned on Basil (who showed no aggression towards the other cat whatsoever-more curious than anything) and started screaming nasty aggressive at him.
This went on for about an hour, Basil couldn't go anywhere near her without her getting nasty. He was kind of freaked out by her.
After about two hours she finally calmed down and things got back to normal.
They've been outside on the lanai a couple times since, and one other time the stray cat appeared, and she had the same reaction.
This week theyve been out on the lanai twice, while the boyfriend was home but not I.
Suddenly this week, shes just started using this nasty aggressive growl almost all day anytime he gets anywhere near her. She's fine with us, but I almost feel bad for him, he looks so sad and worried. They haven't spent anytime together, she seems annoyed and agitated with him. If he gets close enough she grabs him and bites him!
Do you think spotting this stray cat around has made her on edge and irritated with Basil somehow?
I hope she calms down soon, shes scarey when shes mad!
