We've worked with our vet. Meds either are too strong or make her relax.. then VERY INQUISITIVE..then they wear off too soon. Have tried: Acepromazine, Benedryl,Alprazolam,Composure,Zylkene, Rescue Remedy, Feliway,Calm cat food. We are trying Amitriptyline...I worry about it's side effects. 5mg isn't enough. So the Vet said to give 5mg every 12 hrs for 2 weeks before travel. Has anyone had similar experiences with your cat OR this med?
