Shes five and a half months. Its not about the money it's the Convienience. I dont slways need tp do abig zoo plus order. The supermarkets only sell felix or ehiskas kitten. She has Felix to fall back on. My question is what is in Felix kitten thats not in a good quality adult food. She eats her big sisters food happily. Ive got trays of posh german stuff that shes not interested in. If she carries on with good quality dry can i start feeding her the sisters NM?
