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

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

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.

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.

She ate it!

My cat is not really picky when it comes to sprinkling things on her food. For example, I give her hyperthyroid medication every day and she barely seems to notice

My cat is not really picky when it comes to sprinkling things on her food. For example, I give her hyperthyroid medication every day and she barely seems to notice as well as MiraLAX in the mornings and she still doesn’t care. For some reason when I tried to give her glucosamine capsules sprinkled on her food she looked at me like I have betrayed her. Thankfully, chewy was able to respond and refund my money and I was able to donate those capsules to my local shelter. But THESE, these treats she goes crazy for. I would argue she might like them just as much as she likes her greenies. What a relief and I can’t wait to see how her arthritic back legs improve after a week or so on these cause I was reading that they’re pretty effective relatively quickly.

My cat eats these like they are candy.

She started showing improvement after three days. She now moves around more and even plays now and then.

I’ve giving them to her as directed. 2 treats a day for four weeks then one a day for her arthritis. The first day you could tell she felt better. Wasn’t limping like she was and just seems more content. I recommend trying them as directed. They’re working for Abby.
