Milk is vital especially for newborn kittens as they are not able to consume anything else during the early stages. Even older pets can benefit from drinking milk on occasions. Unfortunately, some cats may develop lactose intolerance if fed with milk as consumed from the supermarket.
Hence, alternatives to regular milk should be looked into. They can come in powdered form or even in ready-to-drink formulas. No matter the choice, they bring great nutritional benefits either as the regular meal for growing kittens or supplementary nutritional additives for adult cats.
