Mika is a boy!

This has happened to me too! When I first got my dog Dillie, she was still a puppy and her belly button was an outie. Because of that, we all thought she was a boy, until we took her to the vet and the vet told us that he is actually a she! We didn't have to change her name though. I named her Dill after Tommy's brother from Rugrats, and so we just addied the "ie" to make the name more feminine.

On a side note, when I first read your discussion title, I thought you were referring to Mika the British singer LOL! My mistake!

My grandmother took her cat to the vet to have her fixed. They called her at home later that day and explained that the cat was a boy not a girl so my grandmother said well fix him anyway.

Well, I've owned many cats in a very short period of time [ We had 10 at one point!]. I don't think we ever mixed up their genders though. Male cats are a bit more hyperactive than female cats from what I have experienced, but don't let that put you off, they still enjoy a cuddle.

thats happened to me a couple of times but ive never had a gender preference on cats i love all of them the same. so the first time this happened was about 16 years ago we got a super fluffy kitten from a friend well we had made a vague guess that he was a girl but once he went to the vet they informed us he was a boy. then only a couple months ago one of my cats had 3 kittens which we thought were two boys and a girl but when they were about 8 weeks old it became obvious it was three veeerrryyy rambunctious boys. i must say my boys are more cuddly than the girls.

Well we never really had that problem with cats, but at one point I had a rabbit that we thought was a boy...named him Boo from To Kill a Mockingbird, and rabbits are known for reproducing often. We also had a female, so we took him to get fixed which doesn't seem too common. The vet called us two days later and told us our boy rabbit that was actually a girl passed away. I guess they didn't care enough to be observant either.
As far as caring if I found out my pet was the opposite sec than what I thought, it's still the same pet I know and love...Doesn't change much, just a name which is easily adjusted.

yes, a friend gave me her cat because she said she couldn't look after him any more, so i took him, his name was denis, then a few weeks after i took denis he started to gain weight, i put it down to good eating, then one day i came home from work and founf 5 kittens in my bedroom, denis was actually a she and my friend got rid of the cat because SHE was having kittens, so i changed her name to Willow, sadly she passed away a few years later of old age, but i really thought that denis was a boy....

Lol!! How funny! Male or female shouldn't really change, female cats are said to be sweeter but it's not always true, I really met male cats sooo sweet! As long as he's in your house, you cuddle and treat him well, he'll just be a puffy toy.:)
Congrats on your new kitten!

Yes, tat happened to once with on of my litters. Somehow thought there was 2 females and a male.. granted one male and the female looked very much alike. maybe I picked up female twice when I did initial assessment of gender.. Anyway, the male in question here was actually quite a small statured cat to begin with. So, it wasn't until he was about 7 months of age (and lucky for me he had not received a name yet.)
that I noticed his head start to get bigger as Tom cats usually do. That Is when I realized she was a he.
And not too long after that he told me his name. Yes, you read tat right, he told me his name.. I was looking at him and all of a sudden the letters LJ popped into my head. Almost as if someone had said them out loud.. so I looked at him and said what does that stand for? Little John.. His head came up and he came right over to me..
I currently have 2 boys right now that are about 6 months and no name.. I am waiting to see if they tell me.. but I am starting to feel bad when I call them boy 1 and boy 2. And there brother Ben has had a name for months and already responds to it..:(
