Cat breathing heavy after being given antibiotics

Don't arbitrarily medicate your cat without knowing for sure what the problem is. Also is the antibiotics for cats or humans? NEVER give your cat human medications or the remains of medications for your other cats. Is there mucus in the nostrils? If so, then do a steam tent. Boil some water in a pot, while the water is starting to heat up and boil, get a large towel or blanket so that you can sit under it with your cat. When the water is boiling take it and sit with the towel over you and hold the cat in your arms with its head in the steam so that it can breathe in the moisture. It will help break up the mucus. Also if you have eucalyptus trees near you, gather a few leaves to put into the boiling water. The oil from the eucalyptus tree works so well as a decongestant in humans and animals. Do the same with this mixture as you do with the plain boiling water. Make sure that the cat gets the benefit from the steam and be careful so that the cat doesn't get burned by the hot water or the pot. You can do this frequently during the day. Also, if your cat has a particular spot where it sleeps put the leaves in the spot. Not only is eucalyptus a great decongestant but it also is wonderful for keeping fleas off your animals. I have also used a Vick's inhaler for my cats when they are seriously congested. It opens the breathing passages and makes them comfortable. Make sure that your baby is eating. If she isn't, then you are going to have to force her to eat. I know it's been a few days since you started the discussion and it is very important for the cat to eat. Put whatever wet food you feed her in a blender with a touch of water so that it will puree to an easily handled mush. Then get a dropper or if you don't have too much opposition from the cat, use a teaspoon. Then put some food in the corner pouch in the cats mouth and gently hold the mouth closed and rub the throat so that they swallow. It sounds mean but when a cat can't breathe they can't smell and if they can't smell they won't eat. One of the best books I bought for the critters is by Prevention magazine. The title is: New Choices in Natural Healing for Dogs & Cats. It's well worth having on your bookshelf. One big thing that I will repeat:NEVER GIVE YOUR CAT HUMAN MEDICATIONS!! Cats are very delicate and giving them human medications can and will kill them. It's far better to not even think of giving them anything from the human medicine cabinet. Things like a Vicks inhaler is okay because it isn't taken internally. Is there anything in bloom around your home? It could be allergies. I had a cat that suffered from allergies horribly and I kept the Vicks inhaler close at hand through the spring. The inhaler is a short plastic tube that has a strip of felt with Vick's vapo rub on it. It makes it easy to use when you're stuffed up because it fits into the human nostril very easily. If you don't want to buy a small item, allowing the cat to get a whiff from a jar of vapo rub is just as good. But I would try the steam ...and the eucalyptus first.

Take your cat to a vet full stop. If you care for your cat, you have to do right by it. Tell your vet or they will see, take the package of the antibiotics also so they know whats in it, it may not be serious but then it may also be serious. Get someone who knows what they are doing, self mediciating your pets is not good idea, unless its just de-fleaing or worming. Vets train longer than a doctor think about it, they know what they are doing.
