It really urks me to see "oh i can't keep him" or "oh we are moving and aren't allowed pets" that to me is not nor has ever been an option, and yes, I rented before too !!
Many years ago, I moved back to FL from NY. I found myself unhappy being back in FL and took a long weekend to drive to Greensboro, NC to visit some friends and look for a job to relocate with my 2 adult cats.
Found a pretty decent job, gave notice to my landlord, my job, put in for a rental truck to move, called all utility companies, etc. But I could NOT find a place to live with my cats. My friends absolutely did not like cats and moving in with them was not really an option anyways.
At the last minute, called my new place of employment, called the rental truck company, all the utility companies etc and canceled.
Started a landscaping business and stayed another 7 1/2 years until I met the man who I would marry. Me and 2 kitties moved to CA, where we lost both of them (one to old age; the other to illness) before moving here to MD 6 years ago.
There were not disposable pets and I never regretted my decision. RIP BeBop & Coltrane.
