When we moved into this house a little over a year ago, we brought our dog Princess, who looks like a yellow lab mix, and our 3 cats - Cotton, Lily, and Calico.
Cotton and Lily hate each other (even thought they are mother and daughter). So as soon as we moved in, Lily moved to the woods behind our house and I see her about once a month scurrying through the woods. Cotton and Calico liked each other and hung out on either the front or back porch together all the time.
Then about 5 or 6 months ago, I went to the pound in search of an inside dog. Princess will NOT come inside without us dragging her while she shakes in fear. So we found this cute little pug mix and named him Frodo. He was not a puppy and such a sweet dog. I loved him. Then one day he was outside and we never saw him again. Don't know what happened to him. Saw no trace of him, he just disappeared.
I waited a month or two and we went back to the pound and got a dachshund mix puppy and named her Chloe. She has been more of a pain due to her scratching doors and whining at night. Thankfully we have a 2 story house with a basement and when she is in the basement we can't hear her in our bedroom. I love that dog too. And I haven't seen her since 8:30 this morning. Which doesn't sound bad except that every time we open the door, she comes in, then if we open the door she shoots out, back and forth 100 times a day. Always ready to go in or out.
About a month ago, I worked 2 days in a row and didn't notice until the end of the 2nd day that I hadn't seen Cotton or Calico. Who normally are under my feet trying to trip me whenever I go in or out of the house. And 2 of Cotton's kittens had died, probably of dehydration/starvation. One was still alive and we tried to save it with no luck.
Never saw a trace of either cat.
I don't know what is going on, but it is weird.
Princess is still here. Lily has made an appearance a few times since her rival Cotton is gone. I don't know.
