I have a large yard that is completely fenced off away from the road and private from my neighbors. I have a two story house in a very safe and great neighborhood. I have one cat (12 years old) and one dog (16 years old). Due to their age, they are both very docile and mainly spend the day lounging around and sleeping. My cat (Baby) has her own room that she spends the day in/sleeps in (though I leave the door open for her to roam the house, if she wants to, throughout the day). If I do have a pet who will spend the day with me, I will leave her room door closed and keep the animals apart. She is very friendly but a huge scaredy cat (and will likely hide under the bed if she senses anybody new around). My dog (Bella), at over 16 years old now, is embracing her elderly life with a lot of napping. She likes to walk around the yard to get some sun-bathing time in. Otherwise, she’s very friendly and will likely still just nap/lounge even with the presence of a new animal around. I am happy to allow her to interact with other animals but can easily keep them separate as well. Bella sleeps in my bedroom upstairs and has her own area/dog bed in my living room for the daytime. Any questions, please feel free to ask :)
