Are these soft chews or crunchy? My cat won't touch soft chews and they seem to be all I can find

Answer by ChewyDec 22, 2020
This supplement is formulated as a soft chew.

About how long does it take for these to start working? My cat has been eating them for 2 weeks now and no change. Should I give it more time or buy different product? Thank you. Good thing is that he loves them,he is real picky too.

Answer by ChewyNov 19, 2018
It takes approximately 4-6 weeks to begin seeing results and having to minimize the dosing.

Are these made in the USA ?

Smells like Dark Chocolate

My cat wouldn’t touch these. It says it’s chicken taste but to my human nose, it smells like dark chocolate, I have no idea why. She doesn’t like it and won’t eat

My cat wouldn’t touch these. It says it’s chicken taste but to my human nose, it smells like dark chocolate, I have no idea why. She doesn’t like it and won’t eat them. Unfortunate they don’t have any other flavors for picky cats, especially ones who like seafood. These should be more palatable.

Ever since my little boy has been eating these, he has developed diarrhea, and he now refuses to eat them. previously I had been purchasing these from the local vet, and they were a light brown color...yours were almost black--as if they had been sitting around forever. Please terminate my auto ship for them!

My 18 year old cat, Spike, had quit jumping on the bed where loved to nap in the sun. Started giving these to him daily and within a couple weeks he started getting on the bed again. Also give them to my 14 year old cat, Layla. They love the flavor and eat them up. I will continue to buy them.

The CATS really like them.

My cats are insulted. You asked for their opinion with a bow wow instead of a meow meow. Despite their disappointment they really like the chicken taste.

Something Changed?

My cat used to eat these happily. Then started refusing them. Even minutes before dinner time when he is dramatically "Starving" he won't touch these at all.

Packaging said "For dogs only"

I purchased this product along with some others to help my aging cat with mobility. When I looked at the back of the package for directions I immediately noticed

I purchased this product along with some others to help my aging cat with mobility. When I looked at the back of the package for directions I immediately noticed it said for dogs only, even tho the rest of the packaging has cats on it. The treats are even fish shaped so im no sure what happened there. Also, none of my 9 cats would eat them. They sniffed and walked away. I request3d a refund and was given thankfully. I purchased the Pet Honesty brand and they all love it.

Cat seems to like the taste

My cat seems okay with eating this treat but only if I break it into 2-3 pieces. Otherwise it is too big for him.

Way to large for my kitty

Pieces are too big for a kitty and have sharp edges on the pieces.. my kitty would not touch them.

Bought these for my boy with knee issues. He doesn’t care for them, but my other cat likes them. I like that you only need to give 2 a day versus other brands. These treats are very large and have to be broken down into smaller pieces.
