Recently, I had to move back with my parents for various reasons, but one of which is to save up to buy a home. This process should take roughly a year or so. I don't have anyone with me so my cats (2 cats brother and sister about a year old now) have also spent their last year with me with 10 hours+ of me not being around each day during the week. My mom has 4 cats and both my parents work from home or spend the majority of their time at the house. I am worried that if I let them walk about my parents house, they will get use to having all these other cats and people around and when I go to move out again, they may have issues being back to a quieter simpler life.
Currently I am keeping them in my bed room during the day. It's a larger room than most that can fit a queen bed plus furniture plus a large cat tree and room enough to play on the floor as well. They have a window in my room that over looks the neighbor's backyard (which is always busy and has things for them to watch with dogs running around) plus it looks out into the desert as well. They also have one of their litter boxes in my bedroom and both their food and water bowls so that they can have all they need in my room. When I get home from work at night, I let them out to roam the house for 6ish hours before I go to sleep and bring them back to my room but essentially keeping the schedule of when they are around people and when they are not. Most of the time they follow me about the house anyways our hang out with me when I am on my PC.
I feel bad because my cats are probably bored being locked up in my room. They are use to an apartment to themselves though my apartment wasn't really much larger than my bedroom anyways (basically 2 of my bedrooms). Would it be healthy/safe to keep them in my room in this manner for a prolonged period of time? They would still be fairly young when I move out again but I don't want to screw with their comforts by having them have no one around to 1000 things going on back to no one around again. I also don't want my cats to end up lazy from boredom and crap either. The other main issue is that my mom tends to take over taking care of my pets. What I mean by this is.... if i am not around she will take it upon herself to feed them or sneak treats to them when I specifically ask her not to. She also lets them out of my bedroom before I get home or will go into my bed room to play with them several times a day. This bothers me because again it defeats the purpose of me keeping them in the room and I don't want them to become dependent on her.
