Aging or...?

[Lilpig]

I’ve 2 piggies, who are about 5 years old (I’ve had them 3 years but they were rescues - I was told they were “about 2” when I got them, so they could be older).
Recently the male has been sleeping more than he used tobut it’s been very gradual. No change to eating habits or anything else.

I feel ridiculous taking them to a vet because one had more naps than he used to. Is it normal in older piggies? Should I be doing something?
Thanks!

I think they do slow down as they get older. How is his weight and general look? And roughly how much time does he spend sleeping in a day?

They do slow down as they get older but I’d keep a close eye on him and take him to the vets if he deteriorates. How’s his weight?

His weight doesn’t really vary much at all, never has done.
thanks for your help, I’ll keep an eye on him.
