I need urgent help. My regular exotic vet is unable to get us in for a few days and there are no others around. Yesterday I found a red liquid on my guinea pig and thought it could be blood. Both me and my partner looked for injuries and we couldn’t find any so we thought she sat on a tomato or something. One of her sisters just had to get surgery yesterday to fix her teeth and they found that she needs to get one removed. And about a month ago another one was diagnosed with arthritis (they have all been healthy their whole lives but this months been rough). So I decided to put the three of them in their own section of the cage. This morning nothing seemed strange but when I came back I found this red blotch. I was wondering if anyone knows what this is and is it treatable? All of the piggies are girls and she’s around 7 years old. Sorry for the long post and gross picture it’s just been super rough time for us especially since another one of my piggies died around 2 months ago unexpectedly.
