Economically no. I live in the UK and use Bella and Duke. Not sure if they trade in any other countries. I gave them my cat's weight and for £43.80 they send me just enough food to feed him for a month.

That's a bit pricey compared to supermarket cat food but frankly I can afford it and it's worth it for the health benefits as well as the convenience. Also I can't think of a company I've ever had better customer service from. They called me the day after I received my first box and asked if I had any issues.

From what I've read it can help delay the kidney problems that inevitably come with age. Like I say I've noticed an improved coat but more importantly he doesn't vomit anymore which he used to occasionally and he has firmer, less frequent, better smelling turds.
