How to rehome guinea pigs?

I never thought in 1 million years I’d be posting this but here I am...

Exactly a year ago I purchased two sweet but very shy guinea pigs from Petco. Right off the bat I had to take them to the vet because both of them had urinary tract infections.

They are approximately 14 months old. With that being said I found out ow as pregnant shortly after I brought them home. Now I have a 5month old and I just feel like I can’t give my piggies what they really need anymore... I feel sick to my stomach posting this but I truly believe they would be better off with people who could bring them out to play.

I have a baby who qualifies as “special needs” so I’m constantly at doctors appointments and to top it off I’m in college full time. I feel really horrible but they deserve more attention that I can no longer give them :/

How do I go about rehoming them?
