Complicated background I will try to keep succinct.
I sometimes look after friends' 2 cavies who live separately in two halves of an already small cage. They also have small outdoor runs that aren't very weather proof (measuring about 20" by 30").
Friends go away about 15 weeks a year, if I look after GPs in winter what with the bad weather and design of the outdoor runs the GPs will stay inside their small cages all day every day.
I don't feel very comfortable about their care, I'd rather they could get out and really run around most the time, but it's not practical for me to have them loose in the house a lot. So I am thinking to say no if asked to look after the GPs in winter, just so I can not think about them being cooped up indoors all the time.
But their owners are very good friends, I hate letting them down. Am I being silly, GPs maybe don't mind being in a small cage all the time?
