In June I found out my guinea pig Mickey had a tumor not knowing if it was possibly a cyst, I went to the vet and sadly told me that it was a tumor and there was no form of removing it without it growing back, this left me with knowing she was either going to live until she got to the point it either grew so large it ended her systems from working or it gets infected and causes her to die from that. The vet then suggested that once I saw her suffer I should put her down and that's what happen today a month later after that appointment. Mickey got to the point that her tumor was moving her left leg to the side and also had the tumor hit the floor making it get bloody and have feces all around it considering it was near her anus, at night I would hear her make noise of pain and uncomfortable, I couldn't take the sound of knowing my pet was suffering. Today I went to the vet and that's when the choice was made to have her be put down just the vet examining the tumor she saw how it now getting infected and starting to bleed. She was sadly put down having the vet give her gas and then put a needle through her heart to inject the liquid that would end her life. I was so devastated when I saw her dead body those happy eyes were now dull and I felt so guilty and selfish for making this choice but I know it ended her suffering for good and now she's with her partner in heaven again, and this time there's no tumor that puts her through pain, this time my two guinea pigs are both healthy and happily eating hay together once again in the sky. I will really miss her just having her cage out of my room makes things feel off and just makes me cry for my piggie
