Lots of pets are at risk of catching diseases because their owners don't have enough money to pay for vaccinations.
So vets are trying to get pet-owners to protect their pets from illness by getting the jabs they need.
But some pets don't like going to the vets - and some can put up quite a fight when you try and get them in a carry box.
Does your pet protest about a trip to the vets? Or is it really well behaved?

"With my cat it takes three people to get her in the cat basket. One to hold the head, one for the box and the other to push her in! But no-one escapes without getting bitten."
Dylan, 11, Miskin, Wales
"No-one likes going to the doctors, and it's the same with animals and the vets. I think that lowering the price of injections is a fab idea!"
Emily, 13, Leicestershire
"My dog once had to go to the vet and the only way to get there was in my dad's van. Now she never goes in his van anymore because she thinks she's going to the vet!"

"My dog Rio is a golden retriever. When he needs to go to the vet he does tend to wriggle away to the door but he doesn't do that anymore he is calmer than he used to be."
Katie, 13, Wales
"In the recession no-one can afford to give pets vaccinations, so surely humans should come first or they should be made cheaper. Who agrees with me?"
Billy, 12, Florida, USA
"Yes! This is a big problem for me and my hamster. I hate the vet."
Teo, 12, London, England

Naithan, 11, Newcastle, England
"My cat wails all the way to the vets but he loves the attention. The vets thought he had a heart murmur but it turned out he was just purring because he liked the vet. My other cats don't like the vet though and Miffy walked over the computer and weed in her box."
Jasmine, 14, West Sussex, England
"My dog attacks the vet!!"
Katie, 12, Barnsley, England
"My dog, Cassie, seems alright but she hardly has any problems. My snake and guinea pigs have never been the to the vet yet and we have had them for a couple of months!"
Mollie, 11, Liverpool, England
"My cats get nervous about going to the vet, my current oldest cat Toby is more scared of the journey there though. He meows constantly and presses his head against the roof of his cat carrier as if to try to escape.
For our barn cats, the vet comes to see them which is a lot better than attempting to catch them and take them in. One of our dogs hates the vet and has to be muzzled, while the other seems to not care less what the vet does to him.
Our horses are usually alright around the vet, though one of them is so scared she has to be sedated just for a check over."
Chloe, 13, Northern Ireland

Charlotte, 12, Kent, England
"My dog had a problem with its leg and even to make an appointment at the vets was expensive. When I got there they told me that there was nothing they could do. If I wanted them to have a proper look at it then it would cost just under £1,000 which is ridiculous."
Frankie, 12, Manchester, England

"If people can't pay then why get a pet?"
Kyla, 9, Devon, UK
"My seven-year-old labrador has eczema. At this time of the year it is quite bad so he is on some tablets and medicines. When a pet isn't vaccinated it isn't their fault, it is the owners'. If they loved and cared for them then they would spend the money on getting them vaccinated no matter what."

Abbey, 8, Doncaster, England
"My dog hates going to the vets, because when he went last time the vet cut his nails, and he cut one of the veins by accident. Now he hates going. Whenever we take him, we have to pull him out of the car into the vets! I'm sure he will get better at going to the vets soon!"
Kelly, 12, Dorset, England
"I have a rabbit called Sushi. She is a dwarf lop and her breed was made to show. Therefore she has teeth problems. Every 8-10 weeks we spend around £80 to file them down. Plus she has two injections a year so she does not come cheap. She hates going to the vet. She lives inside the house as well so she is one spoilt bunny."
Lois, 10, Manchester, England
"My cat sooty has arthritis."
Catherine, 9, Derbyshire, England

Kara, 12, Scotland
"My cat Marie doesn't, because she's been so many times, and is so calm and relaxed. But my bunny Twix is a different story! She gets so annoyed that it's quite a battle, but we get there with a lot of cuddles, attention and reassuring!"
Georgia, 10, Kent, England
"My dog Inez has a back problem which gives her pains if she strains her back. She had surgery recently, but is recovering really well! She is also very cheeky as she does these puppy dog eyes at the vets one-by-one so they each give her a dog biscuit from the counter! Well it works!"
Emmi, 12, Prague, Czech Republic
"My pets don't have any troubles because my vet loves them and also they give them treats when they are good. I have two horses and they often need to go to vet to help them. I want to be a vet when I am older so I do hope that animals don't have a problem with me. I want the animals to see me as a friend."
Liza, 12, Maidstone, England
