Over a 5-year interval, multiple laparoscopic oocyte retrievals were done in fishing cats (Prionailurus viverrinus), caracals (Caracal caracal) and domestic cats after ovarian stimulation with gonadotropins. From 21 retrievals in five fishing cats, 579 preovulatory oocytes (mean = 27.6) were recovered and 348 embryos were produced in vitro (mean = 16.6). A total of 452 preovulatory oocytes (mean = 25.1) were recovered from 18 of 24 retrievals in six caracals and 297 (mean = 16.6) embryos were produced. An additional 16 caracal embryos (19%) were produced after in vitro maturation of 83 oocytes, 59 of which came from six retrievals producing only immature oocytes. The presence of corpora lutea at oocyte retrieval occurred in each species (1) at a similar frequency (33%) and (2) more frequently during January through May (11 of 15 retrievals) than during the latter half of the year (4 of 30 retrievals). Of the 12 embryo transfer procedures done in fishing cats, one pregnancy (8%) was obtained and one live kitten born after the auto-transfer of 10 Day-6 embryos. In caracals, a total of 46 Day-4 or Day-5 embryos were auto-transferred to six recipients, one of which delivered two live kittens. Then, 109 caracal embryos were cryopreserved before thawing and transferring to nine recipients (mean = 12.1) on Days 5 or 6. From three pregnancies established (33%), a total of three kittens were born. Two to six gonadotropin treatments/oocyte retrievals were done in domestic cats during 1999 through 2003; an average of 24.9, 23.5, 22.0, 23.1, 23.5 and 40.9 oocytes (P > 0.05) were recovered at the first through the sixth treatment cycles from 138, 138, 97, 49, 22, and seven retrievals, respectively.
