Please could someone advise me where I'm going wrong with guinea pigs. 3 weeks ago today I found my male boar passed away he was 3 n a half. Phumonia. I then got given 2 girls happy running around eating playing together until last night noise which I knew was breathing problems rushed to emergency vet and yes phumonia and my baby girl was put to sleep. I can't understand how she got it and I'm blaming myself for this happening twice. They are inside lots of hay and in a big stiutable cage. My other girl is perfectly fine. Any advice would be appreciated. My heart is aching
