Bringing home a rescue cat is emotional. Exciting. Sometimes overwhelming. The first 30 days shape your cat’s long-term health, immunity, and confidence. Many rescue cats come from shelters, foster homes, or uncertain backgrounds. Some may have incomplete medical records. Others may carry stress that quietly affects their digestion and immune system. This guide walks you through exactly what to focus on in the first month: vaccinations, deworming, nutrition transition, and stress management. No fluff. Just practical steps. Week 1: Immediate Health Priorities The first week is about stabilization and assessment. 1. Schedule a Veterinary Checkup Within 3 to 5 Days Even if the shelter provided medical care, a personal vet visit is essential. Your vet will typically: Perform a full physical examination Check eyes, ears, teeth, coat, and weight Screen for fleas and external parasites Review vaccination history Recommend fecal testing for internal parasites Rescue cats often carry hidden issues like mild respiratory infections, dental disease, or intestinal parasites that are not immediately obvious. 2. Vaccination Review Core vaccines for cats typically include: FVRCP, which protects against feline viral rhinotracheitis, calicivirus, and panleukopenia Rabies vaccine Your vet will determine: If boosters are needed If the vaccination schedule must be restarted Timing for follow-up doses Avoid delaying vaccines. Rescue cats may have weakened immunity due to prior stress. 3. Deworming and Parasite Control Many rescue cats require deworming, even if they appear healthy. Common internal parasites: Roundworms Hookworms Tapeworms Your vet may recommend: A broad-spectrum dewormer Follow up fecal test after treatment Monthly preventive parasite medication External parasite control, such as flea prevention, should begin immediately. Week 2: Nutrition Transition and Gut Health Rescue cats often experience digestive sensitivity during transition. 1. Gradual Food Change If you plan to switch brands or introduce new textures such as wet food or lickable treats, transition slowly over 7 to 10 days: Day 1 to 3 Day 4 to 6 Day 7 to 10 75% Old Food 50% Old Food 25% Old Food 25% New Food 50% New Food 75% New Food Sudden dietary changes may cause vomiting or diarrhea, especially in rescue cats adjusting to a new environment. If your cat is hesitant to eat, soft, lickable options can make transitions easier. Smooth, high moisture treats such as FreezPaw wet cat treat fillers can be mixed into meals or served separately to gently introduce new flavors and improve acceptance. Using a Freezpaw enrichment feeder during this phase also slows eating and reduces digestive stress, which is particularly helpful for anxious rescue cats. Explore FreezPaw 2. Focus on High Quality Protein Cats are obligate carnivores. Their diet should prioritize: Real meat as the first ingredient Adequate taurine for heart and eye health Balanced moisture content for urinary support Wet, meat-based options support hydration and are often easier to digest during the adjustment period. Single protein, high moisture lickable treats such as FreezPaw wet fillers can support protein intake while also encouraging licking behavior. Shop Lickable Cat Paste Sticks 3. Monitor Stool and Appetite Healthy signs: Firm but not dry stool Consistent appetite Stable energy levels Loose stool, lethargy, or sudden appetite loss require veterinary consultation. Week 3: Stress Management and Emotional Health Rescue cats carry invisible stress. Moving homes increases cortisol levels. Elevated stress hormones affect immunity, appetite, and digestion. 1. Create a Safe Room Set up: A quiet space Litter box placed away from food Hiding spots Soft bedding Scratching surface A FreezPaw enrichment toy made from 100% natural silicone for safe chewing and sensory engagement This gives your cat a gentle outlet for exploration and self-soothing while they adjust to their new environment. 2. Respect Adjustment Timelines Some cats adapt in days. Others need weeks. Normal behaviors during adjustment: Hiding Reduced appetite Minimal vocalization 🚩 Red flags: Persistent diarrhea Severe lethargy Continuous respiratory discharge 3. Use FreezPaw Enrichment to Reduce Anxiety Licking behavior is naturally soothing for cats. Slow enrichment activities: Provide mental stimulation Reduce boredom Support emotional regulation Introducing a FreezPaw enrichment feeder can make this process easier. Add 5 to 10 minutes of FreezPaw enrichment time to your cat’s daily routine, ideally at the same time each day. This predictable moment of focused activity helps reduce anxiety, builds confidence, and creates a calming rhythm during the adjustment period.

Spay or Neuter Confirmation If not already done, schedule the procedure. This prevents health complications and unwanted litters. 2. Dental Health Baseline Dental disease is common in rescue cats. Ask your vet to: Check for tartar buildup Assess gum inflammation Recommend cleaning if required Early dental care prevents long term pain and systemic illness. 3. Establish Routine Health Habits Healthy monthly habits: Weigh your cat Check ears and coat Trim nails if needed Monitor litter box output Consistency is preventive medicine.
