Hi, this is Dr. Gabby. It sounds like Toby has some aggression and hunting play he needs to get out of is system. Normally wen the cat is jumping you and other cats it is because he has too much energy and needs to get it out of his system.
So I would try to play with him every day to keep him tired. You can use a laser pointer or laser pointer cat toy. No it will not make him blind if it shines in his eyes. That is a myth.
I like to buy the cat toys that are like fishing poles with toys at the end.
Try to wear him out daily.
If he is able to get his play and hunting activity out with you and a toy then he should stop stalking you and the other cat.
It sounds more like excess energy than anxiety.
There is a great show on Animal Planet Channel show called "My Cat from Hell." The cat whisperer, Jackson Galaxy, works wit different cases every week. Many of the cats on the show are attacking everyone and he goes over how to deal with it. Usually once they have ore exercise and get their aggression out with toys then they stop attacking others.
You can watch it on youtube.com if you do not have cable.
I learn a lot from the show.
Here are some examples of it you can watch for free my cat from hell
Does that help? Do you have any additional questions?
