My queen

Question
QUESTION: Dear Doctor Ray
I've been having cats for some years but a few days before i experienced one of the most horrible events regarding my cats . my white Persian queen Princess was pregnant and about to give birth .we were extremely glad and everything was going ok , but at Tuesday morning when we got up we realized that our queen sounds so dull and awfully pale and feeble ,while she was pregnant for exactly 62 days . we immediately took her to pet hospital and over there we get shocked , as due to X ray it got obvious that all kittens are death! we couldn't believe it as until last night(Monday night) we could see them moving and playing inside their mom's womb , and our queen also was totally healthy .
soon they operate her as her situation was so critical . i had asked them to save her womb at least but after the operation they told me that they didn't have any other choice but spaying her ,as some parts of her womb had been destroyed totally due to the infection caused by the dead kittens . they show us some pictures taken during operation that showed her womb twisted four times ! you see, they told us that the part of the womb that had twisted , had included 2 kittens that died soon after this . then it caused the inflections which led to the death of other 4 kittens and destruction of the womb and mom's serious situation .
they said that this might happened few day before as those 2 kittens had been fetid badly , but it was obvious that other 4 kittens were alive till few hours before .
the condition of my queen also was so bad as inflection has made her so feeble as she can't even walk properly . vets told us that she was so lucky that survived .thank God she's started to recover slowly.
we all are in terrible mood nowadays as we had not expected her to be spayed at the age of 2 and half .I personally can't forget the scene of 6 death kittens that i saw inside the operation room . its a terribly sad fact that she wont be able to give birth any more .we are just furious and frustrated as we can't detect why it happened ,and vets also can't say anything about the main cause of this tragedy .
you see doctor , we were so careful and cautious about her . feeding her in the best way and taking care of her days and nights , we had not expected this to happen at all .having inspected on her every time , i can firmly tell you that till Monday night she had not shown any sign of any problem inside . but , at Tuesday morning she had suddenly changed to a pale dying cat !
can you please tell us why it happened to her ? why her womb had twisted four times !? she had given birth at first time when she was one year old , and her second litter was about 6 months before . however , between her second litter and this one once she got pregnant about 3 months before , and then when an irresponsible vet squeezed her while she was about one month pregnant ,she miscarriage . and immediately after that she got pregnant of this last one . can i regard this soon pregnancy after the miscarriage as a main cause of the recent tragedy ?
i must add also that she used to jump on high niches many time each day . even in last few weeks she enjoyed to do so while she had turned so heavy and big. can this be the main cause? should i prevent her to do so? I'm just so needy to know the cause of the tragedy as i have an other queen and i absolutely don't want to experience something same . we just can't understand why it happened as she had given birth 2 times before without any problem .
let me add finally that she is due to an inbreeding . i mean , her brother had mated with her own mom and this lead to the birth of my queen and four other kittens . can i regard this also as a cause of that event?
Thanks a lot for your precious responds

ANSWER: Hi Soheil
This is a difficult question to answer without access to the cat's xray and a detailed discussion with your veterinarian, but the possibility is when your errant vet squeezed your cat in her previous pregnancy he may have cause damage to the womb wall dislodging it from the lining. This would allow the womb to be free floating. Now when she is due to go in labour the womb would begin contractions and this would then cause the womb to twist. As it wasn't secure it would then bend and of course twist trapping the kittens inside. This would cause them distress and end up in their being unable to breathe, resulting in what happened.
I am truly sorry for your loss and at such a young age to be neutered but please remember she is a loving cat and she has given you some nice kittens. She now needs plenty of cuddles and care.
Inbreeding may have lead to some minor internal complications but these would have shown up in the first pregnancy.
So just be thankful she is ok and give her plenty of love OK

QUESTION: As I've another Persian pedigree queen , can you please tell me how often can i let a Persian queen to give birth ? some breeders believe that once in a year is OK and wont harm her in future. some others recommend me every other 18 month .
You see doctor , I really need to know how often should a Persian queen be entitled to give birth ? and how long can i let her do so? i just want to assure myself of my other queen's safety.
Thanks a lot

Answer
Hi Soheil
certainly every year will not harm her, but really you must judge each occasion when she calls. Let me put some questions to you
Are you mating her to produce the kittesn?
What happens to them?
Please do not just mate her because she calls. Be reasonable with her. Every mating takes a little out of her

Keep to one every 12 months and make it a maximum of six litters in total.
Also do remember to use different studs if you can to diversify your line.
