I have a neutered male guinea pig and an un-neutered female that are a bonded pair for the past 2 weeks. The male was always the more friendly and loved cuddles and would happily lay on your chest or snuggle in a blanket. However the last couple of days he's been more reserved, not so keen on cuddles, whereas the female has loved cuddles the last couple of days since we realised she prefers to sit on our laps rather than on our chest. The male is eating and drinking fine, clucking a lot but just doesn't seem as keen on cuddles and is very wriggly when held, whereas he used to stay still. Any ideas?
