Cat & Dog Owners: Feeding Pets Dry Food Reduces Their Environmental Impact

According to brand-new research, cat and pet owners might significantly lower the environmental impact of their family pets diet plans by feeding them dry food rather than wet food.
Dog and feline owners could considerably reduce the environmental impact of their animals diet plans by feeding them dry food (including kibble or biscuits) rather than wet food with greater water content. This is according to a research study of Brazilian pets that will be released today (November 17) in the journal Scientific Reports. The findings highlight how pet owners can offer their animals with sufficient nutrients and calories while feeding them more sustainably.
Worldwide, the population of pet felines and pets is growing substantially. Presently, the USA is estimated to have 76.8 million canines and 58.4 million cats, while Brazil has 52.2 million canines and China has 53.1 million felines. However, the environmental effect of pet diets is unclear.

Feeding a 22-pound dog a wet diet would trigger 6,541 kilograms of CO2 emissions annually, 689% more than a dry diet plan.

Marcio Brunetto and colleagues evaluated the ecological effects– including greenhouse gas emissions, land usage, and water use– of 618 diet plans for pets and 320 diet plans for cats in Brazil. The authors examined industrial wet diet plans and dry diets discovered on the sites of 3 major Brazilian family pet food retailers. These were also compared to homemade diets– either food produced by business, or food cooked by owners in the house using recipes provided by companies. Additionally, the authors evaluated the nutritional and calorific makeup of the different diets.
For all variables, wet diets for cats and canines had the best ecological impact, particularly compared to dry diets. Homemade diets tended to have intermediary environmental impacts, although water usage in homemade feline diet plans resembled dry diets. The authors estimate that a ten-kilogram (22-pound) dog consuming on average 534 calories daily would be accountable for 828.37 kgs of CO2 each year when fed a dry diet compared to 6,541 kgs of CO2 each year for a damp diet plan– an almost seven-fold boost (689%).
Dry diets provided the greatest quantity of energy per gram, while wet diet plans and homemade diet plans supplied greater quantities of protein. In damp diet plans, practically two times as much energy was supplied by animal active ingredients compared to dry diets (45.42% versus 89.27%), which might contribute to their higher environmental impact.
These results highlight the comprehensive ecological effects of pet foods, the requirement to make them more sustainable, and an indicator of how this may be achieved.
