My girl of 40 years (Herman) has suddenly had a personality change. Normally very lazy and stays close to her house, eating and sleeping her favourite choice of daily life. She does not have a partner he died 35 years ago but shares my garden with a spur thigh who absolutely adores her, equally she has no time for him.Since coming out of hibernation she stays at our local toitoises sanctuary in the chiller fridge, her personality has changed. Has laid eggs, 1st time ever charges around garden and now climbs thru my open patio door and moves in. Every day I am frequently putting her out and then finding her in various parts of the house an hour later what is happening????
