The 33-year-old star, who is still under her father Jamie Spears' care via a conservatorship following her public breakdown in 2008, apparently spent the money last year while she was busy working, reported Female First.
According to new financial records filed in her conservatorship case, the "Perfume" hitmaker, adopted a teacup Yorkie called Hannah and a white Maltese in 2013 and spent USD 31,000 on them that year.
The "Oops I did it again" singer also spent more than USD 12,000 on 12 visits to a veterinary clinic and USD 300 on a groomer. A USD 500 bonus to an unnamed pet service was also sown in the records.
