  • Shaniah says...
    My cat was happy to eat it, but she's not picky with dry food at all and is a garbage guts. We weighed down to the gram and used this product for about 9 months and unfortunately didn't see any progress. This could be due to the fact my cat does not like playing and never has, even when she was skinny, so it's much harder to get her to lose weight than the average cat.
  • Sharon A says...
    My 11 year old brown Burmese didn't like this. I guess that's because she's been spoilt with Royal Canin since she was a kitten.
  • Diane says...
    My cat loves it.
  • Kim says...
    Good-sized biscuits that our indoor cats love to eat. They are all fit and healthy with lovely shiny coats and clear eyes.
  • Jordyn says...
    This dry food has helped my well loved (and subsequently round) fur baby slim down and maintain a steady shape in just about a month. No-one likes paying loads for food but it is great quality, does what it's advertising to do and you see the difference from other brands. My boys were on Black Hawks for a long time and switched to Hills and it's the best thing I've done. Highly recommend.
  • Vanessa says...
    Fantastic product for a multi cat house hold. I have one 15 year old female and two 3 year old males all of which are desexed and indoors so prone to weight gain. I used to feed the female the Age Defying dry food but the males preferred hers and wouldn't eat theirs (Adult Light). Since switching to Perfect Weight around a year ago, the female is slimming down nicely whilst the boys aren't putting on any excess. They are all more active, happy (particularly the cranky old female!) and they all love the taste-come straight away! Fantastic formula which I swear by and highly recommend to others.
  • Yngwie says...
    If you have a cat that tends to get just a little tubby or does the rounds finishing off everyone else's food this really is a wonderful product. Our tabby dropped approx half a kilo within a couple of months from switching from Optimal and Indoor to Perfect Weight and has never looked healthier or happier. Congratulations Science Diet on another great option.
  • Bek says...
    Misty had a break for around a month from Hill's Science Diet and being a Russian Blue she put on a little bit of weight in that time. After 2 weeks being on Perfect Weight, she noticeably lost weight and became a lot more active. Highly recommend this formula
  • Diane says...
    I've got 2 fussy cats (a lean 3.5kg 17yo female & a big solid 9.5 kg 6yo male) & they both have been eating up this particular cat food for over a year now & they both thrive on it so that makes it great value for me.
  • Belinda says...
    My cat is fairly fussy and tends to have a sensitive stomach. He's been eating this food for a week and seems to like the flavour and size of the pellets (they are smaller than many other pellets). He also seems more keen on the flavour and comes straight away for feeding.
