Hi Larissa, welcome to bb.
Good for you for considering this so carefully. Everyone has given great advice and covered a lot.
One of the good things about rabbits is they sleep for a good part of the day. This often works well with people schedules as the rabbit is more interactive when they're at home. Also, one feels less worry about leaving it or concern its lonely because they're just going to be sleeping. Rabbits really like routine and adapt to their human caregivers routine.
I'm hoping to go down to the SPCA and interact with the rabbits and guinea pigs there and go from there
Great! I think meeting adult rabbits is the way to go. Baby rabbits are super adorable but you don't always know what you are going to get personality wise. When they reach puberty it can be challenging and then their adult self may be a bit more standoffish then what were like when babies.
Viewing the adult rabbits, you'll get more an idea if their true characters. You'll get to know which tolerate or even like being held. Most rabbits don't like this. We have to learn to interact on their terms but its very rewarding once we figure them out.
I am also dealing with emotional issues and I think a pet could really help.
Definitely. They are therapeutic. I think most animals are. Getting a rabbit helped me. I think a dog or something would have too but it was a rabbit I fell for.
Hope this helps. Whether you decide rabbit or guineapig, I do recommend looking at the shelters.
Alternatively, consider fostering or pet sitting to see how either animal fits into your college life.
