These are only a few of horror stories I received past weeks. Cat lovers that had hoped for a healthy litter, suddenly found themselves with stillborn kittens or an ill mother cat.

There’s a lot that can go wrong when cats are pregnant or give birth, even when most cats deliver without major problems.

Among dozens of possible complications are infections in womb, death of fetuses, spontaneous abortion, development of fetuses outside womb, suffocation of a kitten right after birth, kittens that get stuck in birth canal ... it’s a long list.

For experienced breeders and specialized vets it’s easy to recognize such problems. But things are different for a regular pet lover. Many female cats have only one litter during their life.

If you have a dog or cat that is an escape artist with cross-country travel on its mind, you might want to consider a GPS pet--tracking device. The same technology that enables rangers to follow tagged animals will allow an owner track straying or lost pets. You can choose either a collar design or a backpack type that works with a harness.

Before you rush out to buy a GPS pet--tracking device you need to consider a few things. Firstly, in addition to system having a GPS receiver, a transmitter is required so animal's location can be reported. This usually means a service provider is needed.

Some pet--tracker systems are used with GSM (Global System for Mobile communication) that uses your GSM mobile phone and a SIM (Subscriber Identity Module) card for tracking. Note SIM card provider needs to have a service in area where you'll be using device.

There are various ways of accessing information that your GPS receives. These include via home phone, Internet, and software installed on your computer. Phone access is not recommended and installed software limits your access to information. Internet access to your GPS data is recommended way to go. You just log on, enter your password and your pet is located.
