Hi. No, you don't need a specific breed type food for Caterina. If she is 6 years old or more, any adult or senior food is ok. You will want to feed a high quality food such as science diet, royal canin, or iams for best results. Good luck.

This particular diet is formulated to meet the demands of all life stages, so technically this should be fine for kittens and will be OK to feed them this. However, there can be some problems associated with feeding adult cats this food, because it may contain more calories and make them more prone to obesity.

What's the best food for my new kitten to ensure healthy growth?

Kittens do the majority of their growth in the first five to six months of life but continue to grow until they are around one year old. During this time of rapid growth and maturation of their bones, it is very important to choose a complete and balanced diet with the appropriate levels of nutrients. Diets formulated for growth include those labeled for kittens or “all life stages.” Canned foods promote increased water consumption in cats, and feeding dry food exclusively or in combination with canned is also acceptable. Offering a kitten with a variety of textures early in life can be helpful in minimizing the chance of having a picky eater. Regardless of diet selection, always make diet changes gradually by mixing the old and new foods together over five to seven days and make sure to carefully measure the appropriate portions of your cat’s food. Abrupt changes have a greater likelihood of resulting in vomiting and/or diarrhea.
