Frequently asked questions about 18 inch universal wheel portable pet travel case cat and dog universal pet carri
What cat food is best?
Royal Canin, Hill's Science Diet, Purina Pro Plan — all formally veterinarian-recommended. Wet food daily is important (cats have poor thirst drive — kidney disease is #1 senior cat killer). Avoid grocery brands (Friskies, Meow Mix) — high carb, low quality. Raw diets require veterinary supervision. Most cats need 250-350 calories daily; obesity is the most common cat health issue.
Do I need a self-cleaning litter box?
Yes if you have the budget and want to eliminate daily scooping — Litter-Robot 4 ($700) is the consensus best, actually works as advertised. Alternative: large open boxes (NVR Miss, IRIS High-Sided $40-80) + clumping clay litter (Dr. Elsey's) and daily scoop. Multi-cat households should follow the n+1 rule (3 boxes for 2 cats).
Cat tree recommendations?
PetFusion Ultimate ($170-290) — sturdy, modern look, multiple platforms. CatastrophiCreations wall-mounted systems — best for vertical spaces. Big Cat Trees ($300+) for Maine Coons or multi-cat households. Avoid wobbly $50 Amazon cat trees — cats won't use unstable structures. Sisal-rope posts are essential — carpet posts encourage scratching carpet.
How do I get a cat to stop scratching furniture?
Provide better scratching options: tall sturdy sisal-rope post (at least 32" tall — cats need to fully stretch), horizontal corrugated cardboard scratchers (cheap and effective). Apply double-sided tape or aluminum foil to furniture (cats hate it). Trim claws every 2-3 weeks. Never declaw — it's amputation and causes lifelong behavioral issues.
Wet vs dry cat food?
Both — wet food daily (1-2 cans) for hydration + protein, dry food as supplemental snack or puzzle feeder content. Wet food is essential for older cats and any cat with chronic kidney issues. Dry food convenience for puzzle feeders and travel. Don't free-feed dry food only — leads to obesity in most indoor cats.
How long do cats live?
Indoor cats: 12-18 years average. Outdoor cats: 5-7 years (cars, predators, disease). Annual vet checkups extend lifespan dramatically by catching kidney disease, thyroid issues, dental problems early. Senior cats (10+) benefit from twice-yearly vet visits. Keep cats indoors with a catio or window perches for outdoor stimulation without the risks.
