Speaking of bird food, their diet consists mainly of pellets, seeds, occasional legumes, and sometimes fruit. In other words, cheap ingredients that should not make a significant dent in your finances. Are you the owner of a small canary? If so, 1.5kg of seeds from Passwell will set you back around $16. Are you the owner of a small pup? If so, 2kg of kibble from Taste of the Wild will cost around $42. Plus, you must take into consideration how long that kibble will last. For a small-sized dog like a Yorkshire Terrier, the kibble bag you purchased will only last for around twenty days. However, the seed mix you bought for your canary should last somewhere around four to five months.
