I am 5 weeks, first pregnancy. I swear my (female) cat knows something is up.  She is WAY more cuddly than usual, and seems to be seeking my attention.  It could be that I am lounging around more, since I'm really tired.  But has anyone ever heard of cats (or dogs) sensing a pregnancy?

Re: Pets sensing pregnancy?
I've def heard of it!
My dog had no clue until much later.
I think our animals are sensing it too. My one cat (we call him, the needy one) is always next to me, and my dog actually keeps smelling my belly I thought it was weird at first, but now I see that others have it happening too!
I too, am almost 5 weeks.
My beagle totally knows. The week before I got my BFP she wouldn't leave me alone. She had to sleep next to my stomch. Once I got the BFP I figured it out. Ever since then she has slept next to my stomach everynight and will not leave me alone. She was the same way when my dad died. She would snuggle next to me while I cried and if I started feeling angry she would come be by me. Very sweet and anoying at the same time.
i have 3 dogs and a cat. And one of my dogs lays on my tummy and graows at the others if they come near. she is so over protective of my belly. my cat is overly lovey too! if im not paying attention to him he meows non stop never use to do that.lol
But yes animals know these things. You spike in hormones indicates this just like dogs can sense cancer or seizers in people they can tell your preggers.

Expecting a bootiful baby Girl this Halloween
My brother has 2 Pitbulls and they are really hyper & jump alot. When I was pregnant with my daughter the female would lick my boobs thru my shirt, and stay next to me the whole time I visited my brother, The male would, while I was sitting, stand on his hind legs and rest his front legs on my shoulders, and lick my neck, and rest his chin on my shoulder, and try to sit on my lap! Mind you, these are 100lb dogs! They thought they were lap dogs, mainly the male!
Also, my sister-in-law's Chiuahah would constantly lick my tummy, and sniff me and cuddle me, and this dog didn't/doesn't like anybody except his human dad!
I have always believed they can tell something is different!
There are three dogs and an old cat in our house and when I finally found out I was preggo, I was not home. We were visiting family in another state. But when we came home I noticed an immediate change with all of them. Suddenly, our cat who hasn't slept in our bed, since we first got together, started sleeping right next to my belly. My youngest dog, will not leave me side for long. When she is around me, she has to be very close, if not touching me some how. Our timid middle dog, is now sleeping with us night. Not fun on a queen size bed lol and our oldest dog growls when people come near me. I'm extremely curious how things will play out when the baby starts moving around in there. I'm also curious since they have excellent hearing if at some point they can hear the baby moving or the heart beat.
My dog knew I was pregnant weeks before I knew. I am totally convinced of this. She started cuddling up to me right on my belly and became very protective. She wouldn't even let my husband hug me without making a fuss.
Now, she lays on my belly with her ear to my skin and I really think she can hear the baby moving about. She will lay there and listen to her until she falls asleep. She is also still very protective.
My horse knew. His 18th birthday was April 1. I had a lesson that day, and my usually energetic, sensitive Thoroughbred was calm and easy going and very easy to ride. According to all the estimates, I would have been about a week since conception, but I obviously had no idea. I remember asking him if he was that easy going for my lesson because he was now 18 and felt he had the right to vote in matters. Then I found out a few weeks later. They day after I found out, I was grooming him and he nudged the front of my shirt up and started licking my stomach. He knew on April 1, but just wasn't going to say anything until he knew I knew.
On a sad note, my dog of 16 years knew, and my animals have always known when it was time for them to exit my life. She knew she wasn't going to be a good fit for a baby (she was a fear biter and senility had started to rear its ugly head, a bad combination). She died of renal failure in June, about 3 months after conception. It was just in time for us to adopt this Boxer who gravitates toward every stroller we come across and loves to lick baby toes, a perfect fit for a house with a baby on the way.
