Difficult to Say How good it is as the cat it is for does not seem to be losing weight.

by -

This is for one of our cats.. He was stray for 2 1/2 years, he has now been with us for 5 years and seems to eat everything so it has been very difficult to get him to lose weight he is currently 12.1 kgs. He seems to prefer our other cats dry food but Purina have said we should stick with this one for now.

Good value

by -

Is being eaten happily, but not on this diet long enough to know that it works or not. Hopefully it will help weight loss

Hyperactive cat

by -

These obesity management biscuits obviously taste delicious as they are a great hit with all our cats - there's one snag - our very rotund girl for whom they were intended became hyperactive after eating them so I have had to dilute them with other biscuits.

Purine vetnary diet

Brilliant food both cats love it as well. Although it’s more expensive than normal purina one they only need half the amount. Will always use this product now
