A ‘KITTEN boom' is set to cause a crisis for animal rehoming organisations this summer, a leading animal charity has warned.

As the weather gets warmer and the days get longer, female cats, whose heat cycles are triggered by daylight hours, come into oestrus, also known as season.

Cats as young as four months will be affected by this, which will make them more receptive to being mated.

An estimated 850,000 kittens are born in the UK each year, many of these in spring, and over two million cats in the UK are stray.

This has led to spring being labelled kitten season and Support Adoption For Pets is warning of the knock-on effect that kitten season will have on animal rehoming centres if cat owners choose not to neuter their pets.

Amy Wilson, charity manager, said: “The crisis facing rehoming centres due to kitten season starts now, with many of our partners expecting a significant increase in the number of abandoned kittens.

“It is crucial that cat owners neuter their cats as soon as they are old enough, which is around four months.

“Now the evenings are lighter, cats will roam for longer and venture further away all in search of a mate, and it’s highly likely it will return pregnant during spring if not neutered.”

A cat’s short reproduction cycle causes further concern, with pregnancy only lasting for nine weeks, and females coming back into season just six weeks after giving birth.

And cats can have litters of up to nine kittens at one time.

Amy added: “It’s not surprising we have a huge overpopulation problem during spring and summer, which puts immense pressure on animal rehoming organisations, particularly smaller, local centres.

“If these smaller facilities get handed just one large litter of abandoned kittens, that could be its quota, and it will have to care for these until they are old enough to be re-homed, temporarily turning away other animals in need in the meantime.”

“Those that choose to re-home kittens independently are often desperate, and subsequently give them to homes that aren’t suitable which can result in them still ending up in a charity’s care. It’s a widespread issue for animal charities across the country that only cat owners can really combat by taking more responsibility for their pets.”
