Pets affected by climate change
Pet ownership is a staple in many families worldwide, and estimates suggest that over half of the global population have a pet at home. However, owning a dog, cat, or any other pet might not be as sustainable as many think. We take a look at the environmental impact of pets and explore solutions to make pet ownership a more sustainable practice.
Highlights
1.Climate change affects everything and everyone, including companion animals. Climate change and associated heat and floods is likely to aid the spread of parasites and illness including tick-borne diseases to pets.
2. Heatwaves and rising infectious diseases from pathogens caused by climate change harm the pets we love so dearly – albeit in a much less significant way than most human activities and industries, the pet industry also partly contributes to increasing heatwaves and pathogens.

Fish
Fish struggling with rising temperature
Fish are “ectotherms” – that is, they use external sources of heat to regulate their body temperature. So pet fish are vulnerable to changes in the water temperature of your home aquarium, which may occur during a heatwave. Extreme water temperatures can cause physical harm to fish. For example, it can increase a fish’s metabolic rate meaning it needs more oxygen to breathe . It can also cause changes such as slowed growth and reduced feeding.
Birds
Heat stress in birds due to climate change
Heat stress can change the physiology of birds. For example, research into a wild population of small Australian robins showed during a heatwave, the birds lost body mass and abandoned their nests, and some died. Heat stress can also cause abnormal behavior in pet birds such as feather picking, when one bird repeatedly pecks at the feathers of another.
In hot weather, regularly check your bird’s cage to make sure it’s clean and stocked with food and water. If the bird is in an outdoor cage or aviary, ensure it is shaded. And a shallow bird bath will help your feathered friend cool off.
Dogs
Protecting dogs from extreme weather
Dogs and cats can suffer on hot days. That’s especially true if they are older or overweight, have thick coats and have short snouts/flat faces Heat stress can cause canine hyperthermia, which means the dog’s body temperature becomes dangerously hot. Watch for early warning signs of heat stress such as excessive panting and erratic movements. These symptoms can quickly escalate, leading to heat stroke and possible death.
Cats
Climate change awareness for pet
Like other animals, cats can overheat in hot weather. Symptoms include panting heavily, drooling and a rapid pulse. Like with other animals, if you suspect your cat is suffering from heatstroke, call a vet immediately. Climate change and associated heat and floods is likely to aid the spread of parasites and illness including tick-borne diseases, flea infestations and heartworm. This puts both cats and dogs at risk. In hot weather, the advice for cat owners is similar to that of dog owners: ensure your cat has plenty of shade and water, and put pet sunscreen on their ear tips and noses, especially if the cat is white .
Prevention Tips
- Ensure pets have access to cool, shaded areas and fresh water at all times.
- Avoid outdoor activities during peak heat hours.
- Use cooling products like pet mats and breathable clothing from Ruse to help regulate body temperature.
- Create an emergency plan that includes your pets, complete with supplies and a safe evacuation route.
- Keep pet identification tags updated and consider microchipping for easy identification.
- Regularly use veterinarian-recommended parasite preventatives.
- Inspect pets for ticks and fleas after outdoor activities.
- Keep your garden and outdoor spaces well-maintained to reduce exposure.
