My Cat Refuses to Eat This

I've tried giving cut up pieces of this pill to my cat in a variety of different ways but he really avoids the pill. I was able to get him to eat 1/2 a tablet one time and he doesn't seem to like the taste and now avoids it like it is his life mission. Spirulina has a lot of health benefits and this company seems awesome, it just wasn't a fit for my pet!

My pup loves them. I love the quality. I trust this company a lot.

Too hard for cats

None of my 4 cats would eat these. They have had powdered spirulina and always liked that. These tablets were big. Too big for my cats to eat and really hard to break into smaller pieces. Probably a good product, just not practical for cats.

Spirulina has Powerful Antioxidant and Anti-Inflammatory Properties. Humans are able to get this supplement so why not cats? My kitty hates them & spits them out if not delivered into the mouth properly, but I put one in her mouth on the side--careful never to choke her. I lift her head up until I see a real swallow. Done! Then I release her--now you can eat your tasty dinner! We are very fortunate indeed to be able to have this valuable supplement for cats. Some dogs eat them willingly--cats perhaps not, but worth the effort to put them safely in their mouth & allow them to swallow before they get their tasty supper! Be smart & purchase this & use your smarts to having them swallow this in a safe manner. It's good for them.

The one and only supplement I recently ordered that my GSD puppy Tessa is willing to take . She's on a raw diet and very picky but I shake bottle and she lays there in anticipation of getting this chewable.
