Cat Not Eating? A Vet Guide for FL, NY & VA Pet Parents
Cat anorexia — when it's stress, when it's a $64.99 telehealth visit, and when it's an emergency. A licensed DVM walks Florida, New York, and Virginia cat parents through what to do.
Medically reviewed by Dr. Tiffany Delacruz, DVM
When a cat stops eating, the clock is ticking — cats can develop hepatic lipidosis (fatty liver disease) within 2-3 days of complete food refusal, and overweight cats are at especially high risk. This guide is written for cat parents in Florida, New York, and Virginia — the three states where licensed RexVet veterinarians can practice telehealth. It covers how to read the situation, when a $64.99 video visit fits, when you need an ER, and the FL/NY/VA-specific patterns we see.
Why cats stop eating — the three big reasons
Almost every case of cat anorexia traces back to one of three underlying mechanisms:
- They can't smell food — upper respiratory infection, dental pain blocking the mouth, or oral mass. Cats rely heavily on smell to eat; even a head cold can stop eating.
- They're nauseated — kidney disease, hyperthyroidism, gastritis, pancreatitis, hepatic lipidosis, drug side effect, or chemo. Common in middle-aged and senior cats.
- They're in pain — dental disease (extremely common in cats over 4), arthritis (most cats over 10 have it but mask it), abdominal pain, urinary blockage (always an emergency).
Step 1: triage at home
First 30 minutes — answer these:
- Has the cat eaten zero food for 24+ hours, or just less than normal?
- Is the cat drinking water and using the litter box?
- Is the cat alert, hiding, or vocalizing differently than usual?
- Is the cat male? A male cat that's straining to urinate without producing urine is a urinary blockage — life-threatening within hours.
- Is the cat overweight? Hepatic lipidosis risk is highest in overweight cats — be more aggressive about getting a vet involved.
If the cat is otherwise normal: try gentle re-feeding for 12-24 hours
Warm wet food slightly (10 seconds in the microwave, mixed thoroughly) to release smell. Offer a strongly-smelling treat like tuna in water (small amount). Move food to a quiet location away from the litter box and water. Don't switch foods abruptly — sudden diet change is a stressor. If the cat eats: continue monitoring. If still refusing food after 24 hours: this is a telehealth case.
If any concerns: this is a telehealth case (in FL/NY/VA)
A RexVet video visit ($64.99) lets a licensed Florida, New York, or Virginia veterinarian assess your cat's body condition, hydration status, and gum color on camera; ask diagnostic questions; and prescribe appetite stimulants (mirtazapine transdermal gel applied to the ear is FDA-approved for cats, or capromorelin oral) or anti-nausea medication (Cerenia). Same-day RexVetRx delivery is available in most of FL/NY/VA. The vet can also order recommended bloodwork through a local lab.
When cat anorexia is an emergency
These patterns mean drive to a 24-hour clinic immediately, not telehealth:
- Male cat straining in the litter box without producing urine — urethral obstruction. Fatal within 24-72 hours without catheterization.
- Cat hasn't eaten in 48+ hours, especially if overweight — hepatic lipidosis risk requires immediate IV fluids and assisted feeding.
- Refusing food plus rapid breathing, open-mouth breathing, or pale/blue gums — cardiac or respiratory crisis.
- Suspected toxin or linear foreign body ingestion (string, ribbon).
- Cat is jaundiced (yellow whites of the eyes, yellow gums) — liver failure or hemolysis.
- Cat is hiding, unresponsive, or collapsed.
FL/NY/VA emergency clinics — be ready

Virginia: BluePearl, regional university ERs, and 24-hour clinics cover Hampton Roads, NoVA, and Richmond. Pet Poison Helpline: 1-855-764-7661.
Florida-specific: heat + dental disease
Florida cats see more heat-stress anorexia in summer than cats in cooler states — a hot apartment or lanai drops appetite even without classic heatstroke signs. Florida cats also have higher rates of untreated dental disease (a common reason for not eating) because of lower routine dental cleaning uptake; a $64.99 RexVet video visit can spot drooling, pawing at the mouth, or one-sided chewing that points to dental pain, and refer for in-person cleaning.
New York-specific: stress + IBD
NYC apartment cats are highly stress-reactive — a new neighbor, construction noise, a roommate moving in, even rearranged furniture can drop appetite for days. Stress IS a real cause, but always rule out medical first (especially in a senior cat). NYC's higher rate of indoor-only cats also drives a higher rate of inflammatory bowel disease (IBD), often presenting as gradual weight loss with intermittent appetite.
Virginia-specific: outdoor exposure
Virginia's higher proportion of indoor-outdoor cats brings broader exposure: tick-borne disease (cytauxzoonosis is a serious feline tick disease in southeastern VA), parasites, wildlife encounters, and toxin exposure from yard treatments. If your Virginia cat goes outdoors and develops sudden anorexia plus fever or lethargy, ask your vet about a feline tick-borne panel.
How telehealth fits in
RexVet's licensed Florida, New York, and Virginia veterinarians handle non-emergency cat anorexia via $64.99 video visits. We can prescribe mirtazapine transdermal (Mirataz), capromorelin (Elura), Cerenia (anti-nausea), or famotidine where clinically appropriate, with same-day RexVetRx delivery in most of FL/NY/VA. We can also order recommended bloodwork through a local lab and review results by video. Telehealth is NOT appropriate for urinary blockage, severe dehydration, or any of the emergency patterns above.
Emergency signals
When to contact a veterinarian
- Male cat straining to urinate without producing urine — URINARY BLOCKAGE, drive to ER now
- Cat refusing all food for 48+ hours (especially if overweight) — hepatic lipidosis risk
- Refusing food plus rapid or open-mouth breathing — always critical in cats
- Refusing food plus yellow gums or whites of eyes (jaundice)
- Refusing food plus suspected toxin (lily, antifreeze, human med) or string ingestion
- Refusing food plus collapse, hiding, or unresponsiveness
- Refusing food in a senior cat (12+) with new lethargy or weight loss
Frequently asked questions
How long can a cat go without eating before it's dangerous?
24 hours is the soft limit — if a healthy adult cat refuses all food for 24 hours, contact a vet. 48 hours is the hard limit — past 48 hours, especially in an overweight cat, hepatic lipidosis (fatty liver) becomes a serious risk and the cat needs urgent veterinary care. Kittens, senior cats, and diabetic cats need attention sooner. A $64.99 RexVet video visit in FL/NY/VA can prescribe appetite stimulants for borderline cases.
Can an online vet help if my cat won't eat in Florida, New York, or Virginia?
Yes, for non-emergency cases. RexVet's FL/NY/VA-licensed veterinarians evaluate cat anorexia via $64.99 video visits and can prescribe FDA-approved appetite stimulants (mirtazapine transdermal/Mirataz, capromorelin/Elura) and anti-nausea medications. Same-day RexVetRx delivery is available in most of FL/NY/VA. Telehealth is not appropriate for urinary blockage (a male cat straining without producing urine is an ER visit) or for cats showing severe dehydration or collapse.
What can I do at home to get my cat to eat?
Warm wet food in the microwave for 10 seconds to release smell. Offer strong-smelling foods like tuna in water (small amount), warmed bone broth, or freeze-dried meat treats. Move the food bowl to a quiet location away from the litter box, water bowl, and household traffic. Avoid abrupt diet change. If the cat doesn't eat by 24 hours, contact a vet — don't wait longer.
Why won't my cat eat but is drinking water?
Drinking water with no eating is a classic pattern for nausea (the cat is hydrating but can't tolerate food) or for dental/oral pain (the cat can drink but can't chew). It can also be early kidney disease, hyperthyroidism, or pancreatitis. A $64.99 RexVet video visit in FL/NY/VA can triage and prescribe anti-nausea medication or refer for bloodwork.
Could my cat not eating be from stress?
Yes — cats are highly sensitive to environmental change. New pet, move, construction, vacuuming, new roommate, holiday guests, furniture rearrangement — all can drop appetite for 1-3 days. Stress IS real, but always rule out medical first, especially in a senior cat (12+) or an overweight cat. If a known stressor matches the timing and the cat is otherwise alert, monitor for 24 hours; if it persists, get a vet workup.
Is a male cat not eating an emergency?
If your male cat is not eating AND straining in the litter box without producing urine, YES — urethral obstruction. Drive to a 24-hour emergency clinic immediately. This is fatal within 24-72 hours without catheterization. Other 'not eating' presentations in male cats are not necessarily emergencies but should still be evaluated by a vet within 24 hours.
