Is Five Old?

[Magician]

Watching my 2 lovely lads, Lenny and Aladdin, today, and thinking they've slowed up a bit; they're both less flexible and not as great at cleaning themselves any more (I gave them a bath today for only the second time ever as they're both getting mild impactions sometimes despite my best efforts to prevent this), though both are still happy chatty bouncy fluffs really who will popcorn around their cage and refuse to be caught after play time!
They're five and a half (approximately) so I'd say they're not too geriatric yet but definitely moving towards being seniors. I'm not sure though: is five considered old?

No change in their weights though they're eating more greens without gaining anything, not sure if I should be worried about that or not to be honest. (Both are 1kg).

Is this all normal for pigs their age? Anything particular I should worry about as they get older?
I've had pigs before but it was when I was younger and frankly, they were more my mum's than mine. These guys on the other hand live in my room (on the bottom bunk of my bed!) and I've had sole care of them for ages so am very attached to the little loves!
Piccies (just because they're gorgeous):
(Oh and they have insanely shiny fur so the photos are a tad crap lol, my apologies for that )
Aladdin.....

Lenny:

World's cutest cavy couple.

Although re. the weight maintenance, whilst they haven't lost or gained anything, they seem to have changed shape; much bonier over their hips and spine but still with slight bellies and a good general body condition score (I think). Will add pics.

If they were horses I'd say they'd lost topline!?

I have a beautiful old lady - Merab is about 5 yrs 9 months and she too is a bit lumpier and bonier.
This seems to be normal in aging piggies.
She’s slower than she was but still has a healthy appetite and is top pig of the 3.
Your piggies are very gorgeous and seem normal for their age.

Here’s my beautiful Merab

Older piggies become bonier and somewhat saggier, especially around the hips. You feel around the ribcage whether they are still OK for their current weight/size. As long as you can just about feel the ribs, but not be able to feel every single one or have them sticking out, your boys are OK. it is also normal that they gradually lose some of the extra weight they have had at the peak of lives; the same happens with old humans. Have your boys vet checked if you have any concerns.

5-7 years is the average life span for guinea pigs, but they can get older.

Out of my 30 piggies, I've currently got 2 five year olds, six 6 year olds, two 7 year olds and Calli, who is hopefully celebrating her 9th birthday next month. She is a bit of a tiny arthritic bag of bones by now (at 670g of weight), but she is still interested in life, is tucking into her veg and wheeking for her pellets.

Very sweet boys! The changes you're noticing (loss of muscle mass over the bones, general slowing down) are normal as guinea pigs age. The average lifespan of guinea pigs is 5 to 7 years, so they are getting up there, though not in 'senior senior' territory yet.

This is a reassuring, thank you - I might make a vet appointment to have their teeth checked and a general MOT if they're getting to be more senior.

Your piggys are gorgeous, I love older boars.
