tl;dr- powder dissolves easily and my fur babies love the flavor
After my one fur baby passed away, her sister was lonely so we decided to get another cat. Well that didn't go well as I was told that the cat had been socialized with humans and other cats... Well that was not true. The new cat was scared of my fur baby and well they both ended up getting stressed to the point that the herpes virus became an upper respiratory infection. -__- I didn't know that was a thing. Well both of them are now doing better and still getting used to each other. BUT they do like this supplement. The powder smells kinda fishy which is off putting for me BUT for them, they LOVE it. Lol I mix it into their wet food and they both gobble up their wet food. So apparently, it just taste good to them. They hated the paste that tastes like maple syrup... It was a struggle to get them to eat it. My fur baby hated the chicken liver flavored treats as well. This is the only one that she likes which is great as she has to eat it twice a day. Trying to force feed the supplement was a pain and added stress to my fur babies. The powder form mixed easily into their wet food and dissolves quickly which is great as my fur baby is a picky picky kitty and will stop eating if she doesn't like the food. -__- The ingredients look great and clean and this supplement is vet recommended which puts my mind at ease. Overall, this worked out the best for me and my fur babies as it made life so much easier for them and for me. Thank goodness!!
