If I had money and a cat I would consider buying the cat tracker.
The iSeePet feeder thing is also really cool.
I like the pet DNA necklace thing.
When I first say the photo, I didn't think the ipond was real. That takes it too far.
I hate the "pet translators" because you know they don't work. I feel like it'll just encourage people to get farther away from reading their pets.
Litter robot doesn't look like such a bad idea.
The inverted unbrella is just a stupid idea since quite a few dogs like getting wet, and I'm sure the others may not like having that thing over their heads.
