Sharing - what's what's yours is mine and what's mine's my own.

Dear George,
My name is Bob and I live with dogs... Nope, that's not a bad thing, as I have the dogs well under control. You could say I am top dog, except that to call a cat a dog is a terrible insult. It's just a question of innate superiority.
I've been experimenting with their toys lately. Of course, I use their Kongs, the large rubber things which if you are lucky have sticky cheese inside. I can poke my paw in and get out the last fragments. Now I am using their puzzle toys. These are round and have places to hide food. They are bit heavy but I have discovered I can lift them off with my paw.The video of me doing this is at the top of this page. The dogs share: I take.
My point is, George, should these be sold for cats? I'm pretty fed up with the cat toys which are meant to look like a mouse, but don't. Or the ones that are too heavy to bat about. I'd prefer toys with food in them.
Yours,
Bob,
PS. We have something in common. My human pretends to be an animal behaviourist. Click here for details. You have laugh, don't you, at their pretensions. Poor dumb creatures.

Dear Bob,
I have posted a photo of myself here, using my own food toy, well mostly of my backside, because my head is inside the cardboard - nearly but not quite stuck. I was fascinated by your video of using that dog toy. I don't think that my celebrity cat friend, Tilly, would be big enough to make it work.  
If your human wants to spend money on you, she could buy you the Play-N-Treat ball, the Armitage Good Girl Cat Treat Ball, the Pipolino (a bit heavy), or better still the Cat Activity Funboard (too small for Maine coon paws).
Better still, get her to make her own. Lavatory paper inner rolls, cardboard boxes are easily made into toys. There are some photos on www.catexpert.co.uk under indoor cats. Of course, I got my head stuck into one of two of the toys, so I had to get my human to make sure the holes were either too small for my head or too large for it.
I agree with you about these so-called human behaviourists. It really is a good joke to see them try to understand us. Poor dears.
Yours
George
PS. I was pleased you made the point about sharing. We cats do not share. I have never let my human into my cat bed and never shall. Of course, I let her share her bed with me - what's hers is mine.
