Coincidence? Or something more?

This may be just a case of pure coincidence.. but I’m not so sure . Maybe something more. First, my mother and I were both Gemini. Sign of the twins. And I was born on my mothers birthday. She and I were extremely close my entire life. Connected beyond explaination. My mother died from breast cancer on February 22, 2012. My chihuahua, who loved my mom and my mom loved her. She lived another 5 years after my mom had died. Until she past away on February 21, 2017. (A day before my moms death date) I found it kinda of interesting but didn’t really put a lot of thought into it. Nearly a year passed, after the chihuahuas death. When my other chihuahua, the daughter of the already deceased one, came to an unexpected death. She died on February 4, 2018. That evening I realized that it was nearly the anniversary of my moms fathers death which was on February 6, 1999. (2 days after the second chihuahuas death, but many years before) if that makes any sense lol So basically my pets died nearly the same days as my mother and her father had died. 1-2 days difference. After we started talking about this, I realized that my 14 year old lab had died in the month of February and 2 of our cats had died mid month of February. None of those had any significant resemblance in date other than the month. Maybe February’s just a bad month for my family? Lol
