ive had to female rats for about 7 months they hate the sound of hoover but i thought theyd get used to it yesterday i was hoovering living room and they started running round cage freaking out and squeeking took me ages to settle them then the smorning i noticed one had a red mark under her right eye ive read that this can be porphyrin and can be caused by stress which could be the case after what happened yesterday so im looking for advice on how to deal with with this the rat im concerned about isnt keen on being handled at best of times shes stubborn and wont let me near her eye
