Change of Behaviour

I have noticed a change of behaviour in Alex recently.

It started sometime last week, I think. When he tried paw Dim Sum. She fought back & he jumped on her. She somehow managed to get away.

I didn't think too much of the incident, until earlier this week. When he tried the same tactic on Carma. He would corner her, then paw her & if she resists him, he will jump on her until she crouches in a submissive position. Then he backs off.

This has been happening over the past few days. He keeps trying to dominate both Dim Sum & Carma. I wonder what causes this change in a cat from a sweet & gentle feline to this.

Luckily he's wise enough not to make a pass on Beauty. She's bigger & heavier & she'd probably pound him if he tries to be funny. She'll probably give him an equivalent of a black eye.

He has also become demanding of my time. He would stick very close to me, wouldn't allow Carma & Dim Sum to come close. When I do play with either girls, he would butt in, demanding to be played. Hmmm.

Nevertheless, I am concerned & how I wish there is an explanation for this change ...
