Curiosity killed the cat!

how can your piggy ‘sense’ that you’re seriously ill, or will be shortly? And if she is to do that, doesn’t that mean she has to be near you constantly? Sorry, just trying to figure it out in my head.
You really need to expand her space as well. The minimum is 2x4 c&c (or 120x60cm) cage for one, or two females. I hope that you will really look at getting a friend in for her as soon as is possible. If space in the cage is lacking, you could potentially set up a permanent play pen around the cage, which they’d have 24/7 access to. Then when the new cage comes in (sizes as above) you could then put them in there after bonding in the play pen/cleaned out cage area. Do you have any rescues near you?
