Owning a pet and cognitive vitality

Owning a pet stimulates the mind and has a positive influence on cognitive decline in late adulthood. The precious animals are a form of therapy that has been proven to boost cognitive vitality.​

 

Pets are a great distraction and a form of stimulation that combats loneliness. Dogs and cats have a knack for knowing how we feel, and stroking them is calming; it releases serotonin, prolactin, and oxytocin in the brain - they are a tonic (most of the time).

 

Comparing dogs, cats, birds, and fish.

 

It is well documented that the social stimulation facilitated by dogs and cats can be linked to slower cognitive decline experienced by their owners. Adriana Rostekova works at the lifespan development psychology research group at the University of Geneva. In a study, she examined the relationship between pet ownership and cognitive decline.

She specifically looked at the distinct roles of owning dogs, cats, birds, and fish and found there were notable differences between the species. Keeping fish or birds showed no meaningful link to changes in cognitive decline, but there were obvious links with cats and dogs.

She explained, “A fish or bird’s short lifespan may potentially limit the level of emotional connection one is able to develop with the pet fish. Bird ownership may negatively affect the owner’s sleep quality due to increased noise levels, which has been shown to be associated with cognitive decline.”

She added, “It is further possible that interaction with dogs and cats provides unique cognitive stimulation, which may be less pronounced in other, less demanding pets.”

The difference between interacting with a dog and a cat.

Pets are incredible; they can increase confidence, bring back happy memories, and have been known to have healing powers. Their little faces and adorable features can melt your heart and leave you pinned to the sofa whilst they lie across you, being pampered, and you talk to them like they are a small human that can understand. 

A four-legged friend can bring joy to your life. Dogs make great companions, boosting activity levels, showing unconditional love and loyalty. Cats can be more choosy, independent, and agile. They come and go as they please, sometimes ready to dive on your feet, day or night. 

Dog or cat, your furry companion may test your patience, poop at an inconvenient time, or throw up a fur ball on your clean carpet, but they can improve mood, boost energy, and help to fight against cognitive decline as you age. 

When interacting with a dog, it has been found that there is an increase in prefrontal brain activation and stronger attentional processes and emotional arousal. Interactions with cats activate the prefrontal cortex and the inferior frontal gyrus, which is linked to the characteristic, hard-to-predict temperament of the cat.

Caring for a dog offers many opportunities and can open up a whole new world. Walking a dog is good for your physical health, it is a great way to meet new people and an excellent conversation starter. ‘Walkies’ is a wonderful bonding time, helping to keep you and your dog fit. Playing ‘fetch’ helps with hand/eye coordination, and a dog can make you feel safe when you are at home alone.

Owning a cat allows more independence; they don’t need a walk, just space to roam and a cosy place to sleep. Curled up in a ball on an owner’s lap or stretched out on a bed, sometimes, they seem to think that they are helpful when making the bed, diving under the sheets and being a furry, cute nuisance. A gentle purr can be comforting, and the ‘kneading’ or ‘making biscuits’ can be a lovely bonding moment between owner and their cat.

 

Don’t rush out and buy a dog or cat without serious consideration.

Pets entertain us, keep us company, and give a sense of purpose and responsibility. They can offer unconditional love and bring happiness and laughter. Owning a pet can create a daily routine and help lower stress levels and blood pressure. They can create positive emotions, improve mood, and bring calm.

The bond between a pet and its owner can be so special and rewarding. That special bond comes at a cost, a responsibility, and the ability to give a pet the attention and commitment that it needs.

What considerations are there when buying a dog or a cat?

Owning a dog or a cat is a financial, emotional, and physical commitment. Lifestyle changes will be necessary. Also, you need to consider, if anything happens to you, who would take responsibility for your pet?

Are you thinking about getting a dog or a cat? Here is a list of things we think are important to consider.​

  • Finance - can you afford to buy and care for an animal? 

They need food, health checks, and vaccinations. Can you afford pet insurance, vaccines, and an identity chip? Would you be able to pay vet bills if the pet became ill?

  • When buying a dog or a cat, you should give the animal a health check when you see it. 

Does it have clean eyes, ears, nose, and bottom? Is the fur soft, and are there any sores on the skin or signs of fleas or ticks? Is the animal limping or skinny? What are the conditions of its teeth and gums?

  • If you are taking in a rescue animal, you should ask about any health issues or behavioural problems. 

Is the animal good with children? Does it have separation anxiety, and why is it being rehomed?

  • You need to do research on the different breeds and temperaments of dogs and cats to see what would be best for you and your home. 

Are you aware of common health issues for the breed you have chosen? Are you going to use a reputable breeder or rescue home? It’s really important to find out as much as you can about the breed and breeder

  • Can you provide a safe and appropriate environment for the dog or cat?

Will the dog have access to outdoor space and places to walk? Do you have appropriate fencing and gates to prevent the dog escaping

  • Do the people living in your home have allergies or fears?

If they do, make sure you have appropriate medication such as antihistamines in case a person has a reaction

  • Have you got the time to commit to the health and welfare of a pet?

 

Bringing a dog or a cat into your life can be one of the best things you’ve ever done, and help with cognitive decline, but it’s not just about you and what you want. Can you give the animal the love and care it deserves?
