The new 3month old kitten, LEO , eats from the older cat, COSMO's bowl. He does not eat out of his own bowl!! So, I know it is very important to give LEO kitten food as he is a baby. Normally, COSMO eats indoor cat formula of NUTRO (reduces poop smell, by the way!!) and I was giving the kitty the kitten formula NUTRO. Is it ok for a while if I just use kitten food so the baby gets the necessary nutrients? Will it hurt the older cat? Any other solutions? By the way, I keep the food out all day . As alway, thanks everyone!!
