I feel horrible! My boys got into the guinea pig cage today and took them out themselves. Now Yoshi's back leg is curled up underneath and floppy and he can't walk on it and it's looking pretty non functional. The upper leg is really swollen compared to his normal leg. He's still moving around quite well using his other legs and eating and drinking regularly but there is definitly somethingwrong with his back left leg. Is this something that can heal on it's own or do I have to take him to the vet? I feel so terrible! Has this ever happened to anyone else before?
