I have a 1.5 year old Bengal stud. He had a litter of 4 and the a litter of 1 around a year old. In the last 6 months, I’ve tried to breed him to 3 fertile females with no success. The last round I think he completed the mating because 2 females didn’t come back into heat for 8 weeks (they were obviously not pregnant though, no miscarriage). This time I’m not sure he’s actually finishing the job. He mounts them and tries for awhile but seems to give up without the females reacting like he’s finished. He has been to the vet and is in very good health except a mild gingivitis that I’m treating. He tested negative for FELV/FIV. BTW, I am a TICA registered cattery and have asked my mentor but she never encountered this. I’ve talked about it to my vet, but she’s not a reproductive vet. I’m trying to find a reproductive vet but so far haven’t found one that evaluates male cats.
