Rat and Mouse Gazette: Nursing Care (1996)

Author: Mary Ann Isaksen Original Publication: May/June 1996 Issue

Most rat owners will eventually encounter a period where their pet requires specialized nursing care. Whether it is a critically ill rat needing medication, warmth, and assisted feeding, or an aging rat requiring comfort, specialized attention is vital.

Note: Euthanasia should only be considered for elderly rats if their quality of life has vanished or they are experiencing uncontrollable pain.

🏠 Housing and Hygiene

The environment of a sick rat depends heavily on the severity of their condition.

Bedding and Environment

For those in critical condition, ~~standard shavings~~ should be avoided. Instead, use:

Old towels
T-shirts

Warning: These fabrics must be swapped frequently. If urine accumulates, it can worsen respiratory distress.

Thermal Regulation

Rats with severe respiratory issues often struggle to maintain body heat due to low oxygen levels. To manage this:

Wrap a heating pad (set to low) in a towel.
Place it under only one side of the aquarium.
Drape a towel over half of the top to provide a dark, warm sanctuary.

Action	Status	Reason
Heating pad under whole tank	❌	Rat needs a cool area to avoid overheating
Heating pad inside cage	❌	Risk of electrocution via chewing
Room too hot	❌	Risk of dehydration

Grooming and Sanitation

A sick rat often stops grooming. While seeing a rat groom again is a positive sign of recovery, you must assist them in the meantime:

Cleaning: Use a damp cloth to wipe away urine to prevent skin burns.
Stress Avoidance: Do not rinse the rat under a faucet. Avoid the noise of hairdryers or running water, as this stress can exacerbate the illness.
Disinfection: Clean the habitat and accessories with a mild bleach solution or a germicidal cleaner like Parvosol. If using bleach, ensure the tank is thoroughly rinsed and dried.

🍎 Nutritional Support

Weight loss happens rapidly during illness. The goal is to provide high-fat, high-calorie foods that the rat finds irresistible.

Recommended High-Value Foods:

Fats: Avocado, peanut butter (thinly spread on crackers).
Grains/Starches: Cooked pasta, instant oatmeal (especially Maple and Brown Sugar).
Proteins: Eggs (scrambled in butter/margarine or hard-boiled and mixed with mayo).
Baby Foods: Vanilla custard, fruits, cereals, and dinner blends.
Fruit: Bananas.

Assisted Feeding Techniques

If the rat is too weak to eat independently, hand-feeding is necessary.

Equipment Needed:

3cc syringes
6cc syringes
12cc syringes (Note: Always keep these in stock before an emergency occurs.)

The Transfer Method:

1. Fill 12cc syringe (easier to load food due to larger opening).
2. Push food from the 12cc syringe into a smaller syringe.
3. Use the smaller syringe for actual feeding to avoid awkwardness.

To prevent boredom, offer a variety of flavors. A suggested rotation includes:

Avocado mixed with mayonnaise.
Mashed banana (enhanced with vanilla and sugar).
Nutrient-dense baby food.
Vanilla custard baby food.

Hydration

Avoid water bowls, as a sick rat may tip them over and become wet, worsening their condition. Instead, administer a sugar-water solution via syringe.

Hydration Formula: $\text{Solution} = \frac{1\text{ tsp sugar}}{4\text{ oz water}}$

💊 Medication Administration

Rats are discerning eaters; unlike dogs, you cannot simply hide a pill in cheese. Medications are delivered via drinking water, orally, or by injection.

Water-based meds: Only effective if the rat is drinking normally.
Liquid meds: Best administered via a 1cc tuberculin syringe (needle removed).

Oral Administration Steps

The Grip: Hold the rat in your non-dominant hand. Place your thumb and forefinger around the chest, just below the front legs.
The Stabilizer: Use the ring and pinky fingers of your dominant hand to hold the front leg on the side you are feeding from. This prevents the rat from pushing the syringe away.
The Delivery: Gently insert the syringe tip into the side of the mouth, behind the teeth.
The Pace: Release the liquid slowly. If the dose is large, pause between small amounts.
The Position: Keep the rat's belly facing you until the medication is swallowed.
