We brought a lovely new 8 month old kitten into our family about a month ago. We have a 2 year old girl already. We did a 3 week introduction (separated with sanctuary room etc.) and everything has gone perfectly, except one thing. Our cat loves the kittens food. Their food is in separate rooms, but I still find my older girl eating it. She waits for the kitten to eat she isn’t bullying her at feeding time and I have made sure the kitten is eating by shutting the door for awhile so the other can’t get to it. I’m not free feeding. But my older cat just won’t eat her adult food. My question is should I just feed both kitten food until our kitten is an adult in about 3 months?
