Animals grieve like people do. Ask anyone who’s lost a pet in a household with multiple animals. Just like humans, each animal deals with loss and mourning differently.
When my cat Edison ran away in July 2013, I was devastated. I had a bond with Edison that was unlike any bond I’ve ever had with a cat. I mourned his loss for quite a while, and to be honest, I still do because I don’t know what happened to him.
Shortly after Eddy went missing, my younger cat, Sadie, became very depressed. She started howling everyday, multiple times a day. She became less active and started to gain weight. I sought help from my vet who suggested a low dosage of anxiety medications but I decided to get a second opinion.
