AI Review Summary

Many customers reported that their senior cats enjoyed the food and readily consumed it. A significant number of reviews indicated increased energy levels and playfulness, as well as improved coat health. Many cats experienced digestive benefits, including a reduction in vomiting, regurgitation, or general stomach upset. The kibble size was frequently noted as appropriate for older cats, and the quality of ingredients, specifically formulated for seniors, was often appreciated. Several cats transitioned to the food without difficulty, and the resealable packaging received positive comments. Some customers also observed general improvements in their cats' overall health or positive changes in weight. Conversely, a notable portion of cats disliked the food or were particular eaters, refusing to consume it, and a small number experienced adverse digestive reactions such as diarrhea or vomiting.

A bit expensive.

I have a 14 year old cat that does well on this food but for the price point, I don’t necessarily think it’s worth it. I can get better quality food for much cheaper!

My boy is happy

I started my senior cat on this a couple of months ago and he seems like he is happier and has more energy. He's been more vocal and more affectionate. I think the food is playing a part in that! I'll definitely keep him on it and hope to continue to see good results.

She's A Happy Girl

Hill's Science Diet, Adult 11+Senior Dry Cat Food My girl seems to really like chicken flavor, She gets excited when she hears the bag open, the kibble is perfect in size for a senior cat, and since the switch over from the previous brand, the Hills Science Diet seems to satisfy her, and the almost daily regurgitation has stopped, Her coat is shiny and healthy, and she's been much more playful, I also appreciate the easy-to-open packaging and the convenient PRESS-LOK closure that locks in freshness. Hills Science Diet For Adults 11+ Seniors is the brand we will stay with *Lean muscles supported with high-quality protein *Made with natural ingredients *Made in the USA with global ingredients you can trust *#1 Veterinarian Recommended

Perfect For My Senior Fellas!!

Science Diet Feline Adult 11+ is a wonderful dry food product for my 2 Senior Fellas. It's made with the best quality ingredients, full of extra vitamins & minerals The Boyz need at their age too!! They both favor chicken over any other protein, so they gobble it up. It's a lil more costly, but well worth it, to ensure my Babies overall health & wellbeing.

Definitely one of my cats favorites!

After trying this brand of cat food for the past month, I can definitely tell that my cats feel better eating it and really seem to enjoy it. They have less furballs or vomit-reactions compared to previous foods they have tried. The ingredients are great, and I love that the bag has a resealable zip-lock opening, making it easy to move around and less worry about the cats breaking into it!

Her coat looks great

My old little lady absolutely loves anything chicken so she is more than happy to eat this right up. This dry food is a nice supplement for when she's yelling at me for a mid-day snack. After a month her coat looks great and anytime she eats is good news to me.

Loved by old cats!

I have two cats, 11 and 17, and can find it a bit difficult to find them a good bag of cat food due to age and digestive issues but have had no complaints with this food! Both cats started loving this food quite quickly so it wasn’t hard to transition them into this feed! My cats haven’t had any problems while eating this food, I highly recommend this food for any owners with some old cats!

Not a good fit for all my cats.

I have a house full of senior cats, so giving this food a try felt absolutely perfect! Right off the bat, all three cats loved the taste. They happily accepted the slow transition to this food, which was a welcomed start. However, it seemed to affect all of my cats differently. One had absolutely zero issues at all, another cat of mine was fine overall and I only noticed an uptick in the occasional puke, but my oldest senior had a terrible time with it. She ended up with diarrhea to the point where we had to take her to the vet to rule out any other cause. She ended up unintentionally defecating in places she sleeps like her cat tower (which we weren’t able to salvage). The issue resolved when she was switched back to her regular food, so I guess there may be an ingredient that just doesn’t sit well on her stomach. However, I feel like since it was great for one of my cats it could definitely be beneficial for others - just watch out for signs of an upset tummy!

chicken taste, digestive system support

An easy and instant hit for my senior kitty with a particular palette. My cat is getting older, but she is still active and enjoys her food, and I want to keep her as happy and healthy for as long as possible! This Hill's Science Diet formula is made just for her! It's gears for senior cats above 11, and it has all the nutrients to support their lifestyle. I found that my cat took to this food quickly and easily, and she loved the chicken flavor. Incorporating this into her routine was simply, and it was easy on her digestive system as well.
