There have only been 2 F4C males (to date) proven fertile. Has he had any brothers who have proven fertile?When is your female due? I hope you have a wonderful litter of Savannahs and share their pics here!
she is due in about 5-6 weeks No brothers who are fertile though that I know of.

Wondering about the lines behind this boy... if he is fertile. The lines that I am very familiar with having fertility at the F4 level are the Bundas line and the boys from Joykatz Amazing Grace too. Are either in your boy's pedigree then? Oh and there is a line from Sweden TicWildside that had a fertile F4 too...

Usually not, I think they they start to be fertile after 5 generations separated from serval...

so is a male F4A not fertile?
Generally not, there were not too many F4As that proved fertile, probably more of those were kept to try for fertility than F4B and F4C and F4SBT... mainly because as we cross SV to SV you are increasing the Serval heritage... for example my F7SBT male is 4.98% Serval while an F7A would be 0.78125%. But so saying that, an F4A is 6.25% but the F4B male in one of my cat's pedigree is 9.765%. I think that % is the highest we saw being fertile and it was from the one specific line (Bundas).

And then your F4 is a C...so it is probably most likely he has too much Serval heritage to have a big chance of fertility...unless in the chance divisions that happen he just didn't end up with a lot of Serval genes. There's always a chance though... but I don't know of any F3s that ever proved fertile (12.5%).

Even at the F5 level, and the A level, we still saw ~10% infertility. It's not a sure thing at F5A let alone B, C or SBT levels.

so if my guy is an F4A, mom an F3 SV and dad a Bengal.....he will not be fertile? if this is the case do I need to nueter him..?

I gave up on the F4, F5, Fwhatever- a nice breeding boy that looks like a Savannah (not a Bengal, Oriental, or Ocicat) is more important than the Fs.
If a cat is a fertile F4 and is a homely as a mud fence, then it is better off neutered.

Don't fall for the fertility dream. A fertile F4 won't magically produce a serval. I believe that beautiful, wild lookings cats can be produced from lower generation Savannahs and it is beginning to happen.

I am not insinuating that our friend's silver boy in question is homely. I am just saying that it is an impediment to get caught up in percentage.
