Good living conditions can prevent upper respiratory tract infections

Several measures to prevent and treat upper respiratory tract infections in cats, a must-read for novice cat owners! Upper respiratory tract infection (uri) is a highly contagious infection Disease has a high incidence rate in young cats. For every cat-raising family, it is essential to take measures to prevent the occurrence of URI. To prevent and treat upper respiratory tract infection in cats, we can according to its transmission route , starting from aspects such as residence, polluted air, poor sanitary conditions, stress, comorbidities, parasitic infections, and malnutrition.

1. Reduce stress

Efforts to reduce stress must start from the moment the cat is brought back, because sometimes even Simply changing the cage is enough to induce URIs in some cats. Keeping everything as clean and hygienic as possible and providing housing that does not require extensive moving or cleaning is key to controlling cat URIs. Regrouping cats that live in groups has been linked to the recurrence of URIs. If group housing is necessary, it is more advantageous to use smaller groups than larger groups to minimize the frequency of cats moving in and out.

If you need to keep them separately, it is better to divide them in a large room. Considering that cats need places to hide, reducing ambient noise (especially barking dogs), maintaining a light-dark cycle and a comfortable temperature, and providing toys and scratchable surfaces are also important to relieve cat stress. Unnecessary treatments should be kept to a minimum - handling or force-feeding that may be aversive to the cat must be weighed against the stress caused by these procedures. Increased socialization may help relieve stress and stress in cats, but it must be done judiciously. Taking a cat out of its cage and being carried by a stranger into an unfamiliar room may help relieve boredom in some cats, but in others it may cause intense stress (and also predispose to certain diseases) spread). Owners should learn to observe the cat's reaction to interactive activities and do things such as grooming or petting in the cage, or letting the cat play in a clean, quiet area outside the cage or letting the cat sit on their lap (healthy vaccinations only) For vaccinated cats) etc.

2. Disinfection

The survival time of most URI pathogens in the environment ranges from a few hours (such as FHV-1) to a few weeks (such as Boschii) and can be inactivated with conventional disinfectants. When an FCV outbreak is suspected, strict attention to disinfection is required. Household bleach (5% sodium hypochlorite) diluted 1:32 when applied to clean surfaces can inactivate calicivirus. Likewise, other items used in households as bleach such as calcium hypochlorite and sodium dichloroisocyanurate (Eclozin) have also been shown to be effective at killing non-enveloped viruses. Like bleach, these products without detergent properties must be used to clean the surface before cleaning. Other reagents with proven disinfectant properties include potassium monopersulfate and fast-acting hydrogen peroxide, both of which have been reported toThis reagent has stronger decontamination ability and better bactericidal activity on organic surfaces than other bleaches and related products. Numerous independent studies have repeatedly demonstrated that quaternary ammonium disinfectants are not reliably effective at killing non-enveloped viruses, despite repeated claims and labeling of such products as being effective. Calicivirus is also not reliably inactivated by alcohol-based disinfectants, and hand sanitizers commonly used in shelters may not be completely effective against calicivirus (although they should still be used in all animal housing to protect public health). Disinfectants containing 60 - 90% ethanol and propanol are more effective against calicivirus than other alcohol-based disinfectants. As mentioned above, the stress and risk of contaminant dispersion from cleaning a typical box-style single cat carrier may outweigh the benefits of thorough disinfection. If possible, the cat carrier should be cleaned in the area where the cat lives, and the cat carrier should be thoroughly cleaned, disinfected and dried between cats.

In short, the prevention and control of infection mainly relies on proper feeding and management. The basic principle is to use a well-controlled and well-ventilated environment to minimize emergency situations and dilute the emerging pathogens to the lowest contact concentration. , newly introduced adult cats or kittens should be isolated and observed for at least two weeks, because the female cat may become a carrier and it is not easy to detect, so it is best for the kittens to be weaned at 4 weeks of age; each cat cage should be separated by at least one Meters or above, and with barriers, gloves should be worn when handling cages, and gloves must be changed or disinfected for each cage before use.

3. Housing

Good housing conditions, stress reduction, sense of security, and effective cleaning and hygiene are complementary to each other in promoting cat health. A good home has a direct impact on the health of cats, and is conducive to cleaning and relieving cat stress. Housing conditions may be the single most important factor in the incidence of URI in rescue shelter cats. A recent study showed that only 60 of 1,434 cats sent to rescue shelters in the UK developed URIs while staying at rescue shelters. The cats in this study generally live in large rooms at rescue stations, and can freely enter and exit the indoor/outdoor areas separated by upper and lower retractable doors. The cats are provided with sufficient hiding space, separated garbage and food, and are completely isolated. Noise from barking dogs, and constant care, etc.

4. Treatment

Symptomatic and supportive therapy should be adopted for cats with acute disease, especially those with acute illness should be given sufficient water and nutrients. When rehydrating sick cats, adding an appropriate amount of thymosin can improve the body's immunity and enhance disease resistance. Pay attention to frequently clearing the secretions from the nasal cavity and eyes of the affected cat. You can use spray or saline to help clear purulent secretions. In addition, vasoconstrictor drugs such as 0.25% epinephrine hydrochloride can also be used for intranasal instillation to reduce the amount of serous mucus secreted in the nasal cavity, but it is not suitable for sick cats with mucopurulent secretions. Use broad-spectrum antibiotics to prevent secondary infections, ampicillin is the first choice, 10 to 20 mg/kg body weight, intramuscular injection or oral administration, 2 to 3 times a day. This type of antibiotic has small clinical side effects and is suitable for the treatment of young cats.

If the cat is suspected of having a mycoplasma infection, doxycycline can be used, 5 to 10 mg/kg body weight, orally once every 12 hours. For conjunctivitis caused by chlamydia, chloramphenicol or tetracycline ointment can be used, which should be used at least 4 times a day and should be continued for 2 weeks after the clinical symptoms disappear. Corneal ulcers caused by infectious rhinotracheitis virus can be treated with antiviral eye drops such as trifluridine or acyclovir eye drops, used every 2 hours, and antibiotic eye drops are used alternately. Taking 250 mg of lysine orally, twice a day, can interfere with the replication of herpes viruses and reduce the severity of infectious rhinotracheitis. You can also intramuscularly inject 0.2 to 0.4ml of Polymusk, once every other day, to inhibit the herpes virus.
