Yes. The vet estimated she is 6 or 7 months old, give or take.
My wife talked to other cat´s servants that told her the worst part was when their cats started to cry ou very loud late at night.
The vet said she was too young to be spayed. So we will have to wait a couple of months before she could get this procedure done.
At the moment she is not screaming but meowing in a melancholy way. Probably, tonight she will cry calling the cats upstairs. She never saw/heard them, but I am pretty sure she knows they live there.
She’s not behaving that way, yet. But she lets us take her in our arms without the risk of being maimed/bitten.
Wow! The vet won’t spay her until she’s almost a year old? You have a lot of heat cycles in your future. They can go right into the next one within days of the previous one ending, IIRC.
Here most private vets recommend it at 5-6 months, and the shelters and some rescues will do it once a kitten weighs 2 lbs/1 kg. Though some vets will recommend waiting for the boys to be a year old before neutering (or taking care of their “trouble puffs” - thank you for that @MerelyGifted) to allow their urinary tracts to mature with the intention of reducing the risk of urinary blockages later in life.
No kitten leaves the local municipal shelter with their reproductive bits. They tend to be pretty aggressive about it in an effort to curb the unwanted kitten population. It’s kitten season here, and our local shelter is full.
@BakaNeko definitely get a second opinion. Otherwise, you or kitty’s other servants are going to have to be extremely vigilant she doesn’t get pregnant. Like @Wayward said, here in the US, 5-6 months is recommended. Either right before or just after first heat for girls. Though cat rescues do fix pets before adoption, often quite young, to make sure those cats really do get fixed. Of course, they also have access to specialist surgeons and equipment, so the small size isn’t as much of an issue.
All of our cats were “fixed” before they came home. Two of them were only about 3 weeks old when the surgery was performed - going by the 2.5 lb guideline. We know they were that young because they both came home with us still sporting baby teeth, and one was too tiny to eat kibble.
Others have given opinions, and I agree, around here if stray kitties are walking they get trapped spayed and released.
Search for TNR in your area they are significantly less money for the procedure because that’s all they do it’s almost assembly line surgery the way they do it. In by 7am out by noon.
There’s a lot of debate over TNR, I fall on the side of trying to break the cycle is better than rounding them up and destroying them.
It’s been many years since our indoor cats but we have done some ferals recently. The younger ones go in a large cage in the garage overnight but the older ones just get released, they all do fine.
Unless there are complications (there won’t be) your kitty will be fine.
The vet will give you good instructions. If kitty picks at the stitches, she may need a cone collar (or cape). Or, if she is small enough, a tube sock with the toes cut off. They might just do glue. Recovery is usually very quick
Their recovery is usually so fast and unremarkable. Your little girl will do fine. I’ve had one cat who needed a cone after spaying, and that was just for a couple days until the sutures stopped itching.
Here’s Bitey Cat as a bitty bitey kitten after her spay:
The shelter vet used medical super glue to close the incision instead of sutures or staples. She was about 2 months old, and the surgery was done as part of the adoption process. She hardly noticed the incision at all, so no cone or kitty onesie needed.
Unfortunately cannot find a photo of Super Kitty in his cape. It worked well though and I wish I’d kept it. Could only find a cone for the next cat 6 years on.
Thanks everyone for the good tips. The vet estimated the cat was younger because of her size, I think. I don’t worry about the cat being pregnant or having kittens around the house. We live on the third floor and she doesn’t have access to the street. We know we can’t be too careful, so we will take her to vet as soon as possible.
Tanks for the post-surgery tips. I think I will opt for the cone. I´m not sure She will adapt to vest or cape.
This was our cone baby. He jumped off our second story balcony after he opened the door and knocked out the screen. He was about 3 at the time.
He was a rescue, kind of. Some neighbors of my parents were breeding shar peis and a stray spoiled the breeding, when the puppies were born they were just going to have them put down.
He left us many years ago but he was with us for 18 years. The last picture is about a year before he passed.
They can go right into the next one within days of the previous one ending, IIRC.
- thank you for that
