[BLOG] #QuickFact : The Answer Might Be In The Bladder

🇫🇷 Lire en Français Ici 

I was writing an article recently on reproduction in the male cat.  

And it reminded me of a #QuickFact that you guys cat breeders would be interested in.  

We already touched on how difficult semen collection and evaluation is in the feline species.  

You can read my previous post on this here

There is however a quick and simple way to evaluate if a cat produces sperm.  

The answer is in its bladder.  

No, I’m not kidding ! 

In male cats in fact, nearly 50% of the volume of the ejaculate will end up in the bladder during ejaculation. 

We call this retrograde ejaculation.  

And you now understand that in male cats, it is quite common.  

If you check the male cat’s urine after breeding, that will help answer the question if this male produces sperm or not.  

It is not as good as a full spermogram, for sure.  

But it is still a valuable clinical information. 

That’s the #QuickFact I wanted to share with you today on cat reproduction. 

[BLOG] #QuickFact : The 35 Day Rule

🇫🇷 Lire en Français ici

I received an interesting email today.  

« I’m dealing with a pregnancy arrest in a bitch. Should I do something ? »  

How to answer this ? Well, remember the « 35 Day Rule » .  

In a bitch or a queen, pregnancy arrest that happens BEFORE 35 days post-ovulation will lead to embryonic resorption.  

Understand that dead embryos will literally be « digested » by the uterine walls.

You will see nothing. You might not even notice if you did not do an early pregnancy diagnosis.  

I wrote a blog on this, you can read it here.

If pregnancy arrest happens AFTER 35 days post-ovulation, you will typically observe an abortion.  

Which means that this time, YOU WILL SEE « something » – blood, organic debris,…- coming out from the vulva of the bitch/queen.  

In the case of an abortion, your veterinarian might need to help the expulsion of some of the material in the uterus.  

Typically however, this is not something required when dealing with an embryonic resorption,  

That’s what I call the « 35 Day Rule ». 

And it is the #QuickFact I wanted to share with you today on canine & feline reproduction.
