Mr Johnson's Advance Rat & Mouse Food

A rat and a mouse need different portions even when the food in the bag is the same, which is why both rows of this feeding table matter.

Mr Johnson's Advance Rat & Mouse Food is a 750G complementary dry food. Wheat comes first, followed by barley, wheatfeed, oats, soya bean meal, sunflower seed meal, calcium carbonate, vegetable oil and fat, dried cranberries, mono calcium phosphate, Bio-Mos, sodium chloride and Verm-X herb blend. The analysis states 13% protein, 4% fibre, 4% oils and fats and 4% ash, with calcium, lysine, phosphorus, methionine and sodium also declared. Its additives include vitamins A, D3 and E plus iron, manganese, zinc oxide, copper, iodine and selenium.

• 750G complementary dry food for rats and mice
• 13% crude protein
• 4% fibre, 4% oils and fats and 4% ash
• Wheat and barley lead the composition
• Dried cranberries are listed in the recipe

Match both animal and age. Growing rats are listed at up to 28g daily and adults at up to 25g; growing mice are listed at up to 10g and adults at up to 9g. The manufacturer calls this a guide and directs owners to add suitable fruit and vegetables, a small portion of cooked lean meat a couple of times a week, and fresh water at all times.

Who it's for: rat or mouse owners who want a complementary single food for either species and will use the separate growing and adult quantities rather than treating the animals alike.
