Our guinea pig died last night. She was 4 and had a lump that was discovered over a year ago but had coped very well with it. She has always still been very active and eating well until recently.
2 days ago I noticed she was off her food and was keeping an eye. Yesterday with the heat I had put a bottle of frozen water in her cage to help keep her cool and put her in the coolest room in the house. I came home to find her in the corner of her cage and assumed all fine but an hour later found her lying flat and lifeless but eyes open. She had a pulse so we wrapped her in a wet towel and tried to give her water by syringe but she passed shortly after.
I am gutted that she may have died from heat exhaustion which may have been prevented. My dh thinks it may have been her tumor that took her but it's hard to know.
It was very difficult not hearing her squeaks this morning when I came downstairs for breakfast.
I would say that anyone who has pigs be very careful with them in this heat.
