Hello! My cat, Zippers, is nearly 12 years old. She has a nervous disposition generally, but since seeing a cat outside (2 nights in a row about a month ago), she has become obsessed with staring out the windows during the night to see if any animals are in the backyard. We live out in the country with 2 acres of land. We had to put opaque cling on the back patio doors so she wouldn't sit and look all night out of them. Now she only has one window she can look out. And she does nightly. I already have two Feliway plug ins going (we always had one going but I added another recently). During the day she seems fine (of course she mostly sleeps). Is there anything else I can try to help reduce her stress? Any suggestions are welcome!
