This vacuum is a bit expensive, but does a great job. It still costs less than the Cat & Dog. It's also a bit heavy and might be hard for some people to push around but if you had Dyson Animal before, it wouldn't be a problem. In fact this vacuum will be a bit lighter than the Dyson Animal. I have two shedding dogs and a long hair cat, so I needed a vacuum with great suction. The bags are a little pricey, but will hold a lot and they are filtered and lock when you take them out, so no dust flying around. It's very quiet, not like most vacuums I've had before. The hose comes off the main vacuum to vacuum crevices and corners, or whatever you need to reach and stores right back in. Pros: does a great job, it's very quiet, has a long cord, hose is easy to release and use, seems sturdy and well built, the head swivels easily, bag is easy to change.
Cons: expensive (but I consider it a good investment since I won't have to keep buying new vacuum every couple of years), may be a bit heavy to push (but if you had a Dyson before and you were fine with the weight, it won't be an issue for you), bags pricey (but last a long time and will hold a lot). I would recommend it.
