We had 3 guinea pigs all girls and they were litter mates all of which were really close. They all live in luxury indoors in our sons room but regularly come out for a wander around/cuddles. Unexpectedly one of the Guineas died on the 1st July and now the other 2 are not eating hardly anything and mainly staying in their sleeping quarters. They are so quiet too, they use to squeak like mad when they heard us go upstairs but now it’s rare although a few more squeaks this morning. They aren’t really eating their nuggets and have a range of fruit and veg given to them A lot gets left but they can be tempted by a little bit of cucumber and have eaten a bit of hay but still so little compared to normal. The vet says they could be grieving. Anybody have any ideas on how to help them. All the advice on the internet is from people going from 2 to 1 guinea however we have gone from 3 to 2 so a little different. Desperate to find a way to perk them up. Our ds absolutely adores them and has been devastated to lose one. We have told him to leave them to be quiet for now and keeping a close eye on them. Any thoughts appreciated!
