I have another rat question for the resident expert :) One of my rats I adopted in January passed away a little over a week ago leaving her buddy without a cagemate. She's about 16-18 months old now. Would you recommend a new buddy for her or let her stay solo (with lots of extra attention from me) for the rest of her life? This is the little girl who is very shy & timid. She doesn't really do out of cage time, but seems to enjoy hanging with me as I talk to her. Tough call. Any advice would be welcome-thanks!
