BOSTON (CBS) – Two teacup Yorkie sisters are in need of surgery and places to live. The MSPCA said Oreo and Misa, who can almost fit in the palm of a hand, both have painful joint problems that a previous owner was unable to handle.

Oreo’s back knees are dislocated, and Misa is losing blood in her femur bone. The MSPCA is trying to raise more than $4,000 to offset the cost of their treatment.

“We’re hoping that generous individuals will donate toward Misa and Oreo’s care so we can get them past this phase as soon as possible and into wonderful new homes,” said Anna Rafferty-Arnold, associate director of MSPCA-Angell’s Jamaica Plain location.

Their surgeries are expected to take place next week. After that, they’ll be ready to meet potential adopters.

The MSPCA said that even though they are sisters, Oreo and Misa would rather live apart.
