my kitties are so full of kak, they refuse to eat proper vet food, preffering whiskas(from when they were rescued). they do like the super expensive fancy feat wet cat food and of course the purina pouches....
We used to feed ours Whiskas too until I ended up with vet bill just over R5K. Switched them to Purina One after that. Apparently it's the flavouring of Whiskas that tricks the kitties into loving it so much.
