Our normally skittish but friendly male neutered 8 year old cat has got progressively more badly behaved throughout my pregnancy. Since I've been on maternity leave he's somehow got even worse- he's spraying in every room (having to follow him round with a cloth!), attacked our other cat and has scratched her face quite badly, and then bit the health visitor 
The feliway plug-in which normally calms him doesn't have any effect, and he gets plenty of love and cuddles but still seems stressed out. Am starting to get really concerned about what he'll be like when the baby comes 
Has anyone had any similar experiences with pets who can give any advice or reassurance? Feel like I've tried everything!
