Finally got Kaz, my foster, booked in to be spayed next week, but i am a bit unsure whether the age we thought is right. Have just checked dates, she was taken to the rescue on thw 29th Apr, i got her on the 26 May, so they had had her a month and she hadnt come into season, but they thought she was 8 months old. It took her until the 14 June to come into season, so 6 weeks to come into season, and she only came into season once. Is this normal? with their reckoning she would be 10 months old now, am going to get the vet to check her. Blackie seemed to practically be constantly in season, she was the only unspayed cat i have had.
