Hello. This morning one of my sister's guinea pigs passed away. Both guineas are female. It spent its whole life with another. As they are very sociable animals, we are worried that the remaining one will get lonely. I was just hoping for some advice on how to help the remaining one continue to live a 'normal' life. However, as my sister is getting older, we will not be getting anymore once the last one has lived it's life, so we will not be introducing a new guinea to this one. We have given it a soft toy which is about the same size as it, a suggestion that I've seen many a time on the internet. I came on here to ask if there are any other ways of keeping it happy for the remainder of it's life? (Note: they both recently turned 4 years old). Any suggestions would be highly appreciated. Thankyou.
