I had to put my cat down on August 3. Because I live alone I knew how lost I would be without another animal so I got another cat within 4 days. I still miss my other cat. I had her for 18 years. I got her when she was 4. She had been with me through everything including my mom's death. She was the last connection I had to my mom also. I knew though that I had to go on and didn't want to deal with the world alone. The new cat doesn't replace my other cat and never will nor does it diminish the love I had for my other cat. It just feels up the emptiness in my life and she is so lovable.
I am so glad you got another companion. It will help you heal.
