ALL of my gang will be getting microchipped soon. I will do it myself at the shelter i work at (i microchip animals all the time:bighumb:So i'd rather to it myself. It is $15 per animal to get microchipped at the shelter, and then you fill out some more paperwork and there is a filing fee of about $17 if i remember correctly. So about $32 give or take a few dollars
And just in a side note- ALL of the shelters in our area check for microchips! In out shelter alone, countless animals have been reunited with their owners thanks to them being microchipped- including several who got their collars off. Had they not been microchipped, their owners would have probably never found them. It is soooooooooo worth it!!!!
Also, one more thing worth mentioning....when your animals is microchipped- if they are getting spayed/neutered the same day- have them microchipped while under anestesia (it takes a whole two seconds) but it will save the kitty some stress since it'll be asleep for it. Also- make SURE the tech or vet who microchips the kitty/dog holds the skin taunt and down while they pull the needle out (slowly!) so that the chip does not come out. Right after the pet is microchipped, they'll wave a scanner over that area to make sure it took. Make sure it takes before you leave after having your pet microchipped just to be safe. It does not hurt the animals - true, it is a rather large needle- but since cats/dogs have rather thick skin, it is not painfull for them- it will only cause minor discomfort for a moment or two - then they'll forget all about it
/ Also - keep an eye on the area that was microchipped for any signs of irritation or allergic reactions- if you see anything out of the ordinary- have a vet look them over to make sure the injection site did not get infected or that their bodies did not reject the microchip (this is VERY VERY rare- but i wanted to mention it)
