LunaPig has developed a swollen toe - middle one on her left back foot.
It doesn't appear to be inflamed, filled with anything yucky or causing her any pain. The swelling feels quite solid.
We've bathed it with salt water a few times this week and it did appear to shrink a bit at one point.
Any ideas what it could be and whether or not a trip to the vet might be necessary? She's absolutely herself otherwise.
