Managing Queens – Gestation

As more interest is being put into neonatal survival, we understand mom’s health is vital. Live kittens are the goal and 50% of the kitten loss happens at birth. As owners, we do not get the chance at saving these kittens so managing the queen during gestation leads to more live kittens' birthed.

Queens and prenatal vitamins:

Single kitten litters have the highest mortality rate and five kitten litters have the lowest mortality rate (Peterson). We have seen this in other species as well. Appropriate litter size leads to healthier moms and babies. They often have single kittens because of embryo loss in gestation.

Nutrition Required:

One study of 477 kittens showed 60% of those with low birth weights failed to survive to weaning. Marginal diets and vitamin deficiency lead to poor uterine health, interference with blood flow to placenta and poor nutrition and oxygen to the embryo. As a result kittens are born weak or smaller than normal which decreases their nursing ability. There is a chance they will be born dead as well. Since kittens have little glucose reserves, anything that interferes with early nursing contributes to kitten death. Nutrition is important in another area; overweight queens have smaller litters and the highest mortality rates. The goal of feeding a queen is kittens that will fight to live.

Prenatal vitamins maximize RBC’s and kitten size in a gestating mom. Kittens are born with all the RBC’s they will have until 6 weeks. Anemic kittens are weak and slow to nurse and anemic moms wear out in labor. Prenatal vitamins such as Breeders' Edge® OXY-MATE allow for improved queen health which in turn makes birthing more effective and timely. The result is more live kittens.

Stress - big issue in queens:

Stress free gestation avoids embryo loss and early labor. Blood spotting is common the first week after breeding but spotting between second and eighth week gestation is a problem. Most queens are so clean that little is seen besides neonate loss (small litters). Dominant female fighting or stress of any kind leads to placenta separation, oxygen shortage and nutrition issues. A female that is stressed leads to early delivery and weak, low birth weight kittens. Queen roommates should not be changed during gestation and any fighting or dominance behavior should not be tolerated. Queen dominance behavior causes submissive queens to have silent heats, nutritional issues from eating last and daily stress. Stress embryo loss makes the submissive queen a challenge to manage effectively in colony housing. Once bred, housing submissive queens by themselves during gestation should result in a successful litter born.

Another issue is safety of mom. When mom is comfortable with the safety of her kittens and knows “you have her back” so to say, she stays with the kittens and mothers them. If she is not comfortable, she is moving them, mouthing them, stepping on them and not nursing them. Get mom ready with a queening area during the last two weeks of gestation and be sure to keep the distractions to a minimum. Show her love so she knows you “have her back”. When she feels comfortable with the safety of the queening area, she will also be comfortable with your assistance if needed.

Queens are much more sensitive to stressful gestation than other mammals. In the queen, stress and dominance behavior will lead to spotting blood (placenta issues) and weak and small kittens. With 50% of our kitten loss happening at birth and small kittens having a 60% chance of not making it to weaning, managing the gestating mom for health is time well spent. The short story is treat her like a “queen” and she’ll bless you with live healthy kittens.
