My peru family Ffwlbri, her sister Tesni and her niece Tegan as well as sisters Heulwen and Hedydd have all made it to 7 years of age without any illness bar a tussle with carried in ringworm for a couple of them; they are all adopted.
Tesni needed an infected burst sebacious cyst right next to her genitalia operated out at age 6 - we'd been hoping that that cyst would be staying put without any intervention because of its tricky location. She still lived another year to celebrate her 7th birthday earlier in the year. The other four are still going. Tegan, the youngest of them, is turning 7 years in two week's time.
The majority of my piggies have been healthy.
Some of the knowledge we have available on here today I and others have had to figure out the hard way by learning from mistakes and failures, but that goes for all of us who are going back a long time when we (and our vets) knew a lot less.
How to do things right when they have never been done before doesn't come with a nice manual or a tidy little map with arrows. New fads need to be tested to work out whether they work or not. And a surprising number of them do come with a 'not'.
New conditions turn up - 5 years ago hardly anybody had ever heard of lymphoma, for instance. 10 years ago, it was just noticed that an increasing number of urinary tract infections were not reacting much to antibiotics anymore but IC wasn't something you'd come across much.
10 years ago, pellets had generally a lot more calcium content and used to be fed in larger quantities, so stones we overall a lot more common. Diet recommendations contained vitamin C recommendations, but calcium and a sustainable calcium balance that included pellets and water wasn't anything you'd find information about. With my first bladder stone piggy I really struggled with a total lack of useful information, for instance.
Healthy guinea pigs in good care (and that includes rescue piggies, even those from horrible backgrounds) can make it to 5-7 years without any major health problems until old age is catching up with them - unless they are unlucky to develop a major health problem, which is never predictable.
Of course we are used to seeing a much higher proportion of illness on here because the forum is a port of call for piggy owners with all kinds of health problems.
It is the same thing that when googling for online health problems you usually come across all the horror stories, but only rarely any of the vast majority of success stories. It certainly tends to throw members who are not aware that they need to correct for that bias.
