As with any pet, rats do cost money each month in order to keep them happy and in good health, I spend anywhere between $40-$80 a month on my 3 boys and that's just for food, treats, cage accessories and extra fresh foods like fruits and vegetables.
That cost goes way up if they get sick and you have to take them to the vet. I had to take one of my boys to the vet and have him put to sleep a few years ago and it cost me $80 and most vets won't let you set up a payment plan. It's either you pay at the time or they won't see you.
I have a credit card that I use specifically for any emergencies for my rats. It doesn't get used for anything else. If your rat gets a tumor and you want to have it surgically removed that can cost anywhere between $200-$300.
Before adopting a rat most people think they only thing they need to buy is a cage, bedding, food and some toys. While those are necessities you also need to think about what you'll need if your rat gets sick, gets mites or lice or an abscess.
List of things that should be in your ratty first aid kit: (Instructions on how to use these things will be below)Neosporin with pain relief $8.00 (this can be applied to small wounds, cuts and abscesses.)
Revolution for cats $17.95 (One drop of this on the back of your rat will get rid of lice and mites)Aquatic Amoxicillan $8.99 (Needed for upper respiratory infections)
Hydrogen Peroxide (for cleaning wounds)
Q-Tips and cotton balls (for swabbing minor wounds)
Eye dropper (for flushing abscesses)
Small diabetic needle (can be given to you by a vet for treatment of dehydration)
Instructions for Diluting and Giving MedicationsMost pet stores don't carry medications for rats so we rat owners have found out that medications for other animals work quite well for out furry little friends if used the right way.
Revolution for cats- it has to be the version for cats because the version for dogs is stronger and can harm the rats instead of getting rid of the lice or mites. You put one drop of the revolution liquid on your adult rats back, between their shoulder blades and then you distract them so they don't clean it or lick it off, until it is dry, one treatment should get rid of all the rat mites or lice they have.
Aquatic Amoxicillin- Mix 5ml of water with a 250mg capsule. That would make 10mg for every .20ml of water. You should give a sick rat 10 milligrams per lb of rat of amoxicillin per day for 14 days.
You would need small diabetic needles which you can get from your vet if your rat gets sick and needs fluids but they won't drink. You would have to give your rat a subcutaneous injection of saline.
There are other costs as well, like hammocks, food bowls, fleece to line the cages with, toys, beds and wheels. I buy new fleece hammocks and bunkers every couple of months because my boys chew them to shreds. I also have to routinely replace the fleece blankets I use as bedding because they chew holes in them.
So as you can see there's a lot more to having pet rats than just buying a cage, bedding and food. As with any pet, if you're not willing to take them to a veterinarian when they get sick...don't adopt an animal.
