Animal centres across the UK are being filled with more and more unwanted cats and kittens.
The RSPCA animal charity says loads of people dump their pets during the summer, but this year is turning out to be a particularly bad one for felines.
Part of the problem is that some owners don't make sure their pets are properly looked after while they're away.
Some owners also aren't prepared if their cats have kittens, so when they do, the new arrivals are abandoned.
Felicity, 13, is a volunteer at the RSPCA cattery in Southall, London, where they've already got more than 100 cats and kittens waiting for a new home.
Felicity told Sonali that kittens can be really hard work to look after
She said: "Some people don't take their cats to the vets to have an operation which would stop them having kittens, so then they get lots of unexpected kittens and some people just abandon them."
Last August alone, one large rescue centre took in more than 1,000 unwanted animals.
The boss of the Southall cattery, Bev, said they'd seen a big increase in the number of cats being abandoned this year, but there's something you can do to help, whatever type of pet you've got.
- If you're going on holiday, make sure you've got someone responsible to look after your animal.
- If you've got a cat, take it to the vet to have it neutered, which means it will have an operation so that it doesn't have kittens.
- If you spot a family of cats that's been abandoned, ring the RSPCA.
