Yes.. that sounds normal...
My girls hear like to have a call... call a bit more...
wander off for a little nap & then call more.
I found with my girls... that if I put them into a large crate
at night & cover them with a blanket they seam to sleep a bit
better... well I get to sleep a bit...
The calling time with each girl differs..
I have one girl here who will call for about 6-8 days if not mated.. yet
another girl will only call for about 3-4 days.
As she is only young it may only be a short call.. but again they
all differ.. fingers crossed !!!
Your neuter boy will certainly...
I like to refer to my moggies as "My Town Purebreds"
Here in WA they are often refered to as DSH or DLH..
domestic Short haired or domestic long haired.
I usually set my birthing boxes up when my queens are about 5-6 weeks pregnant.
This gives them time to check it all out before the big event.
Good luck,
I cannot wait to hear your birth announcement!!!
