hello, I am looking for advice. I have 3 male indoor / outdoor cats. Basil has cardiomyopathy - the left side of his heart is enlarged but he is not showing any symptoms yet. The vet has prescribed half a Nelio 5mg pill daily. The other 2 are healthy. Up until now, we have someone come to the house daily to feed and clean up after them when we go on vacation but she is leaving the area. I did put them into a cattery several years ago but I felt that this was particularly stressful for Basil. Apparently he spent the week hiding under a bed. So ideally I would like to find another cat-sitter. However, if this is not possible, is there anything I can give Basil to help him stay calm while in the cattery? We only go away for a week at a time but I really worry about his heart when he is stressed.
