Beaphar XtraVital Rat Food 500g A complete, premium rat food, made with quality ingredients, and supplied in a gas-flushed re-sealable packet for maximum freshness and palatability. In the wild, rats are the ultimate omnivore. ; However, domesticated rats deserve better, and XtraVital for rats is the perfect complete diet. Seeds and nuts are kept to a minimum, as they can cause skin problems. A small amount of meat is added to replicate the animal protein that wild rats would normally get from eating insects, grubs or eggs. One 500g packet of XtraVital will typically last one rat 31 days. Suitable only for rats. ;
