A while back Hector was wheezy & sneezy at the same time I came down with a cold. As soon as my symptoms came out & I knew I had a cold I got my OH to deal with him so I wasn't coming in to contact/breathing on him. But I think I was incubating my cold when I was in with the hamsters (without realising). It may have been coincidence but I'm pretty sure I gave Hector my cold. If you have a cold & you haven't got anyone else to help you with the hamsters, make sure you thoroughly wash your hands before you go to feed them & be quick like a ninja so you're not breathing in them. Just changing food & water shield be fine so long as you're interacting with them, I think. And if this is more than a hypothetical question, I hope your cold gets better soon
