So it takes approximately 266 days – between 38-40 weeks on average for a typical human embryo to develop. I’m at 22 weeks, and I really should stop griping that I have 18 whole weeks left. But truth be told, we have it easy when compared to some of our animal friends.
I had always heard, “well you should be glad you aren’t an elephant” - now I know why.

Hamsters are pregnant for approximately 16 days. According to the interwebs, it’s hard to spay or neuter a hamster – so encourage your pet hamsters to use protection! (I’m kidding, kind of – if it was only that easy! Just don’t buy a male & a female!)
Mice and rats are pregnant for 21 days. It icks me to even type the word r-a-t.
Rabbits are pregnant for 31 days. It’s spring time – we expect a new crop of rabbits running thru our yards in 31 days people!
Skunks are pregnant for 31 days. That stinks.
My father wasn’t a fan of spaying and neutering his animals. My last pregnancy, he had a poor dog who was pregnant TWICE and delivered a total of 8 puppies – all while I was developing 1 human! (FINALLY, he got the idea and spayed the poor bitch!)
Cats are pregnant for 63 days. Spay or neuter your pets people!
Pigs are pregnant for 114 days.
