14 to 21 days.They can also have a heat cycle ever 2-3 weeks until they are bred.Have you asked your vet about spaying her even though her milk hasn't completely dried up? If not I suggest that you do and get her fixed as soon as possible.Otherwise you may never catch her out of heat.LOL

Be careful with her. I had an indoor cat that got pregnant through a slightly torn screen door.

She can be spayed while she is still in heat, but you need to let the vet know.

"got pregnant through a slightly torn screen door"

Where there's a will...

The other day, I asked a guy what kind of dog he was walking.

The dog was about the size of a Min-Pin, but very muscular through the shoulders & neck, & he barked like a big dog.

The guy said he was 1/4 Chihuahua, 1/4 Min-Pin, & 1/2....

Rottweiler.

He said the female Rottweiler was lying down when his neighbor's ambitious Chi/MinPin came upon her unawares & pounced, but I don't know.

I think those girls have their own needs & probably do some active cooperation.

What was the question?

Oh, yeah.

Take that kitty in to Kitty Planned Parenthood asap!

Sylvia,that's hilarious! What could be more ironic.Finally a Chihuahua that actually IS a Rottweiler!LOL
