Whiskas in Rebranding issues

My cat has been eating the Whiskas in jelly sachets Fish flavors for years. Past few months he's been throwing up and we've been so worried, before a vet visit, we changed brands, and it has since stopped, been 3 weeks with no issues, since the brand changes with Whiskas, something is wrong.

Id even check the rebranding, you're dry food Chicken and Turkey changed packing to only Chicken, but states, same taste? Where is the Turkey, how is the taste the same without this? My cat refuses to eat the new chicken, so clearly its not the same taste/recipe

Whiskas is lying to the public, i might even query if cheaper ingredients are being used so they make bigger profits, considering the issues being reported.

Along with the rebrand, they changed their packaging on dry food, to now exclude the very helpful re-sealable bags, will be changing brands on dry food as well very soon

Using Hello Peter to report this so the public see's this, Reports on places like their Facebook page are not being attended to properly i believe, this needs to be properly investigated
