Cat loves but not sure if they actually work

My almost two year old tabby cat loves Greenies. She has two food and water dishes in the house, one in the kitchen and one in my room (where she sleeps/lounges during the day). In the morning and at dinner time she gets fed in the kitchen and right before I go to sleep I put a few Greenies in her upstairs food bowl. Oh man, it's the highlight of her day. She races me upstairs and then sits in front of the hutch where I keep the Greenies. She'll just meow until she'd fed her Greenies. So as a food, great success. I bought these because my vet suggested them as a suplement to brushing her teeth. If you've ever brushed a cats teeth you know feeding them food is better than brushing.  I don't really think it is helping her breath. She still has bad breath sometimes. I gave this product 4 stars because my cat loves them but I knocked off a star because they don't actually seem to be doing anything for her oral health.

Nothing says love like a cat waking you up at 4 am by throwing up a hairball on your bed.  Right?  Yuck.  One of my friends suggested that I try a hairball remedy to see if that helps, after having this happen to me several times (not counting the time I woke up and stepped in it in the middle of the night).  I was doing a search on Amazon and came across these  and thought I would give them a try.  First of all, let me tell you that my cat doesn't typically like a lot of snacks.  Some she will go crazy for, but others she will not.  As soon as I opened the bag she went nuts jumping up on her hind legs and grabbing onto my hand holding the treat.  They didn't look like much so I figured it was a one time thing and once she tasted it she would slow down but no.  She loved them.  So at the absolute least, they are a tasty treat that my cat will love.

Now, the directions say to give 12 of these at one time.  12?  Seriously?  These won't last long.  The first day I gave her only a few and that night I woke up again to the sound of her throwing up.  Not off to a good start.  However, I have been doing this for a couple of weeks now and so far she has not thrown up.  Its too early to decide whether or not its because of these treats, but so far, the experience has been pretty positive.

I don't know if these are helping yet; only been using them a week, but my cat loves the taste, thank goodness.

You REALLY have to match the treats to the ball. If they are too big, they slide out too easy. If they are too small, they get stuck between the wall of the ball and spiral OR they come out SUPER easy. Thankfully, you can switch to the smaller hole, which takes my cat 5 minutes instead of a swat of the paw to get all the treats out.
The treat I've found best that works are those soft stick treats you break up yourself to feed to your cat. Then I can make them JUST fit inside the small hole, and it takes my cat a while to get the treats out. I think the longest it's taken him is 10 minutes, only because he got the ball stuck behind a blanket and I had to come help him get it out. He gives up too easy sometimes XD.

My cats absolutely love these, though I am not sure if they are actually working to help with plaque build-up on their teeth.  With only visiting the vet once a year, we will see if these actually do anything when I next take my youngest two in for an appointment in May and their teeth are examined.  These are certainly easier than trying to brush a wiggling adolescent male cat's teeth, that is for sure.

It's hard to tell if these are good or not because the cat that would eat a sock devours them and my picky eater will only eat it after playing with it for about 20 minutes...if I've successfully kept the other cat from stealing it for that long.  Unfortunately, picky-eater is the one with the hairballs!  They're a good size treat and at 45/pkg, not a bad deal.  I just wish I could tell you if they work!

My cats loves them. Most cats can open the container by knocking it over. Many cats, including mine, can open the cabinet to jump in and knock them down.
This last pack is an ounce less for the same price. But I still buy them because the kitties love them. They do last pretty long, being used just as an extra treat. I don't know if they really help teeth. That was one reason for selecting this brand the first time. Their teeth are good though. The hard chewing likely even helps.

The cat loves these. I am not sure that there were ten in the pack because I cant find a single one anywhere in my home. guess they are just under everything.

The cat I felt could use these originally gobbled them up which was great.  She has a slight limp to her gait that I believe is due to weight gain & old age.  Although she runs to me when I open the bag, she will no longer eat the supplements which is odd because she turns her nose up at nothing... until now.  The other cat I thought would benefit from them is middle aged but with no signs of joint issues.  She on the other hand is frustratingly fussy.  She gobbles these up & is nuts about them!  Because the cat with the slight limp stopped eating them after about a week, I cannot tell if they were of any effect.  After only a week, I doubt they were since these things take time.  Because the other cat has no visible signs of joint problems, again I cannot tell if these have any effect.  She has about 5 days left in the bag.
I firmly believe in natural treatments for animals & humans alike so I'd like to think/hope that they are beneficial.  The only downside besides the weirdo cat, is the fish shaped chews take a bit of effort for the cats to eat.
I also tried these same supplements in the dog version (shaped like bones) for my Great Pyrenees & he loves them.

My cats don't seem to like that they light up when they roll around. My dog likes them, though, for that reason.

my kitty won't eat them consistently but I keep them in my cabinet because I feel like the benefits are great. I think her problem is the think film around the treat. If I peel it off she will eat it more often but I'm unsure if that is a critical part of the treat

I dunno what I think of these.. But the cat absolutely loves them. Have to pick them up at night or he plays with them all night keeping us up. He loves them!

My cat had a different crinkly butterfly that he loved so I thought I'd try these. They do not crinkle much, so if the crinkle is what your cat finds appealing, you might want to try a different toy. These are a good size and are well made, though!

This is so simple. But my cat goes crazy for them! The cat nip that's in the bag with them has long since worn off but he still plays with them every day. Chasing them and carrying them around. Luckily it's a 30 pack so I'm not worried about the 10 I know must be under my couch.
