What is Bio Spot Flea & Tick Collar For Cats?

Bio Spot Flea & Tick Collar for Cats kills fleas, flea eggs and flea larvae, adult ticks (including those carrying Lyme disease), tick larvae and nymphs to prevent re-infestations. This easy-to-use collar is effective against fleas and ticks for up to 7 months of continuous protection. Wetting the Bio Spot Flea & Tick Collar for Cats will not impair the collar's effectiveness or your pet's protection. If your cat becomes wet from bathing, swimming or getting caught out in the rain, it is not necessary to remove the collar. The Bio Spot Flea & Tick Collar also has a breakaway mechanism for added safety to allow your cat to become free of the collar in an emergency situation.

What is this product used for:

Bio Spot Flea and Tick Collar for Cats is designed to kill adult fleas and flea eggs. The collar begins working to kill fleas, flea eggs and larvae, adult ticks, tick larvae and nymphs as soon as it is placed around the cat's neck. Full protection against fleas and flea eggs will be achieved within 48 hours, providing continuous protection for 7 months. Full protection against adult and immature ticks will be achieved within a few days, providing continuous protection for up to 7 months. Adult ticks will be killed over the entire pet. Dead ticks will fall off or may be easily removed.

How this product should be used:

Remove the collar from the package, unroll and stretch to activate insecticide generator. As the collar begins to work, a fine white powder will appear on the surface. Place the Bio Spot Active Care Collar around the cat's or kitten's neck, adjust for proper fit and buckle in place. The collar must be worn loosely to allow room for your cat to grow and to permit the collar to move about the neck. A properly fitted collar is one that, when fastened will snugly slide over your cat's head. Leave 2 or 3 inches on the collar for extra adjustment, then cut off and dispose of the extra length. Collar does not need replacement if your cat becomes wet.

However, flea and tick collars may be immediately replaced.

What special precautions are there:

When the collar is first worn, observe your cat's neck area every few days for irritation. Remove the collar at the first sign of irritation or adverse reaction. Sensitivities may occur after using any pesticide product for pets. If signs of sensitivity occur, remove the collar and bathe your cat with mild soap and rinse with large amounts of water. Do not use on cats less than 12 weeks of age. Humans: Do not open package until ready to use. Do not allow children to play with this collar. Pesticidal dust will form on this collar during storage.

Rated 3 out of 5 by from no problems my cat goof, is doing well with his new flea collar, he still scratches, not nearly as much as he was. I do believe he is scratching his old flea bites.

Rated 4 out of 5 by from Amazed I got my cat back from my family (they had been caring for her untill I could get her allowed on my lease) And she was so infested with fleas and ticks she was misserable. I was horrified! This collar really does work in a matter of days. The day after we put it on her dead fleas/ticks and eggs were falling out of her fur everytime I picked her up or pet her. I don't know if it will last a full 7 months (The packaging does say if the infestation is bad collar may need to be replased after 2 or 3 months instead of 7) But I am relieved to not hear her cry out and then start scratching frantically. She is a long haired cat, 15 years old. She gets just as upset at having the monthly liquid treatments as she does at having a collar put on. At least I, hopefully, wont have to terrorize her with a treatment for 7 months! The smell is HORRIBLE but a very small price for me to pay for her comfort. She is my "companion animal" and I owe it to her to treat her right. The price of 1 collar every 7 months is something I can actually afford on my limited SSI incom. Thank you 1800petmeds for providing this product!

Rated 1 out of 5 by from Its cheap for a reason This doesn't work. Our puppy got fleas which spread to the cat. The dog's fleas are under control with his heart worm medicine and flea baths. I wanted to try a cheap cat flea collar before spending a lot more money on other products, while avoiding topical treatment because my cat doesn't do well with them. I didn't expect the collar to kill all of the fleas, but I did at least want to try to get them under control. We followed the directions, its been over a week. His fleas haven't gotten any better. We can still see large fleas, eggs and larva. yuck.

Rated 1 out of 5 by from It's cheap for a reason Maybe it's good at prevention? If your cat already has fleas, it won't get rid of them.

handling of flea collars

my cats are indoor cats,and i play with them and pet them is there a hazard,because you have to use gloves when putting on the flea collars. thank you fred.
Asked by: Anonymous
Because I am typically sensetive to pesticides (and other chemicals) I simply remember to wash my hands after petting and before eating or touching my face (or other body areas). If you are worried just was your hands.

is it ok to use this collar along with advantix or frontline too, for extra protection or is that too much

Asked by: Anonymous
The packaging warns not to use the collar within 30 of topical treatment. So no, don't do that.

Does this collar have the break away feature?

This feature allows the cat to break free if it gets hooked on something.
Asked by: Anonymous
It says it does on the package. Kiki has not caught it on anything so I cannot confirm with 100% certainty that it actually will.
