Hi everyone i have got 2 female guinea pigs, ive had them from 3 weeks so they are now 4 weeks and a bit! My question is, before i get them they were in with 2 adult females, one baby male same age as them and an older male about 9 -10 weeks old. Ive just read on the internet that guineas can get pregnant at 3 weeks and now I'm panicking! is there any chance the older male could have got one or both of them pregnant? also one of them bit me today and drew blood, I'm very carefull while handling and hadnt been holding her for long, i got piggies because i was told they rarely bite! how can i break this habit? i read pulling the hair on the back of the neck works (like thier mother would do) but thought that seemed a bit cruel?
