My pet peeve is whever other people criticize me and have even called me ridiculous for loving my pets dearly.  They say....."It's just an animal!"  Of course, I don't keep my mouth shut anymore.  
 
Recently, a lady kept asking why I don't have human children?  I basically started to explain.............then I just said it's personal!! 
  
Anyhow, I cannot tolerate ANYONE who doesn't welcome my pet into their home.  I understand completely but if my pet is not welcomed, neither am I.
