The girls went in for their check up today, and the vet saw a marked improvement in them. Penny´s head is more straight and she wasn´t doing circles. The vet thinks it was a virul infection, and the meds they gave them do work with the brain.
Neither of the girls mind being picked up now, in fact Penny demands attention! Patches is a lot quieter. The vet also recommended that they stay in quaranteen another two weeks before I try to introduce them to Natasha. Just in case we see any changes in them.
