Good Senior Food

So far, so good! My male orange tabby is 14, his renal labs are starting to rise. I would really need labs in a few months to know if it will make a difference.

Meh. Big $$ not a big hit.

I have four indoor cats. I’m sure the product is worth the money if your cats don’t have a revolving g choice of dry foods but mine just plain don’t care for this

I have four indoor cats. I’m sure the product is worth the money if your cats don’t have a revolving g choice of dry foods but mine just plain don’t care for this one. So it’s only used as a topper to encourage eating pate’s.

We have two cats and one is very picky. This one seems to be a winner for our two litter mates. They are both indoor and one will eat anything we put down (including her sister’s food). The other one is very finicky and only eats certain foods, both kibble and wet food. This one is enjoyed by both cats and Science Diet is recommended by our vet.

Senior cat food rocks

My two senior cats are 13 years old and love having their crunchy food at night, the bowl is always empty in morning.

Freshness and digestibility.

He loves this dry food, especially when it's fresh. Since I have only one cat I wish it came in smaller amounts, it can go stale.

The shape of the pellets is amazing

The pellets are triangular but with rounded tips and curved sides. My senior cat is 15+ years old and has had teeth problems and these he can manipulate and eat

The pellets are triangular but with rounded tips and curved sides. My senior cat is 15+ years old and has had teeth problems and these he can manipulate and eat. He seems to really like them too. Two other elderly cats I had were very happy with these.

How much my cat loves it!

My cat used to ask for Greenies when I fed him, but he loves the Hill's Science Diet so much, the greenies are out of the picture.
