Great question, Sue. While certain antivenin kits (which contain antibodies against a specific type of venom) may be available in some areas, they are not really practical for the average pet owner, because most antivenins don't deal with all kinds of snakes. They are made for a specific species or group of snake, spider or other venomous creature. If you suspect that your pet has been bitten by a snake, it is best that you seek immediate veterinary care. Attempts to remove or counteract the poison yourself are usually ineffective. You’ll only waste valuable time needed to get your pet into the proper hands. Keep your pet as calm and inactive as possible as you get him or her to the nearest veterinary clinic. It would be helpful to the veterinarian if you could describe the venomous creature’s size, color and markings, but please do not get too close or attempt to capture it. You may be stung or bitten yourself!
