So I already have one ginuea pig that I have had for 3 years alone (a female)and I feel kinda bad like I need to get a another one to keep it company. However I'm worried about the extra cost and the limited cage space I have. Should I definitely get another one or can the one I currently have be ok by itself? Also I feel like the one I own rn is getting lonely and I'm worried about that cuz I here they can die from loneliness
