When I was in college, I lived alone at my dad's house in a rural area while he worked out of town. I had a field mouse (which is a story for M day). I caught one mouse in a trap and had a terrifying experience poisoning another. I will most assuredly come back in my next life as a poisoned mouse with a trap on my tail.
My aunt suggested I get a cat. I did, which took care of the mouse problem. The cat drove me crazy and made me sneeze. It attacked my feet while I tried to sleep and loved to walk on my books and papers while I studied and wrote papers.
My dad thought I definitely needed a kitty door in the garage so my cat could come and go as it pleased. I'm not sure why he thought it needed to go out since I was trying to make it an inside cat, preferably a mouse-eating indoor cat. My dad is like that. He likes to come and go. I imagine he just felt bad that the cat was trapped inside.
The thing about kitty doors is they do not discriminate.
One day I opened the door that led from the house to the garage to bring my cat inside. The second I called my kitty's name, the place was crawling with cats. It was an infestation. I shut the door very quickly. Eventually they left, and my kitty soon had some kitties of her own. I moved out soon after that. My dad's neighbors, an older couple, kindly took care of my cat and her babies.
For the animal lovers out there, I know I should have had my cat fixed, but I didn't know that back then. I'm glad now that I didn't because her babies made my elderly neighbors so happy. I remember them sitting in the yard letting the kittens crawl all over them. The thing that I get now, nearly 25 years later, that I didn't get then is Helen had Alzheimers. The kittens were a blessing for her and her husband. They spent hours playing with them outside at a time when their lives were quite likely very difficult and when Helen otherwise stayed inside. I remember Gene thanking me with the biggest smile on his face, a smile I had never seen before. At the time, I didn't understand why the kittens were such a gift to them. I understand now.
